汽车车身推荐标准1、范围—美国汽车工程师协会（SAE）操作规程建议定义了一套关于车辆尺寸参数的测量和标准步骤。

尺寸参数最初用来测量在设计环境下设计车辆（例如，CAD）。

在本标准中所有的尺寸参数都可用这种方法测量的。

除此之外，一些尺寸参数可在实际车辆中使用。

如果考虑物理特性，在数值上会有一些不同。

但是，要注意衡量标准不要与设计目的弄混。

除非特别说明，除了只适用于地面有关的尺寸，所有的尺寸在与三维参考系中都可以正常测量（见SAEJ182），。

所有的尺寸都是在整备质量下测量的，除非另有说明。

所有尺寸测量于基本型车辆，不包括正规生产选择方案（RPO）或者配件，指定尺寸例外。

即使有许多术语和尺寸用人体部位来命名，它们的各种布置、性能和舒适度与之无关。

2. 参考文献2.1 适用书刊——以下书刊为本标准一部分指定范围的延伸说明。

除非另有说明，否则SAE最新版刊行即将实施这些标准。

J1100 2009年11月International地上车辆推荐标准签发日期：1973年9月修改时间：2009年11月被替换标准编号：J1100 SEP2005（R）机动车辆尺寸基本原理2009版J1100在内容上进行重大修改。

具体而言，尺寸步骤和定义：●与全球汽车生产商信息交换（GCIE）相容；●与其他美国汽车工程师学会乘坐车厢标准修订版本相协调；●与国际标准化组织（ISO）出版的相关定义同步，包括使用HPM-II；●根据美国环保署（EPA）定义的规管程序进行正规化；●与美国国家公路交通安全管理局（NHTSA）规定的联邦法规中的部分定义保持一致。

在本版本标准中，回复了部分先前删除的SAE J1100尺寸，以及一些更老版本的SAE J1100尺寸定义（例如W27）。

此外还采用了很多新的定义、尺寸和图。

因此对文件结构重新进行了调整，以保持更好的一致性，并涵盖进行了修改的内容。

最显而易见的是，无论是否在容量指数中使用行李厢，均加入了与行李厢相关的尺寸，例如长度表——行李厢尺寸长度表——行李厢地面长度从外部尺寸中被去除——L505。

使用第二个后缀以便更有逻辑的整理尺寸编码。

与前两版SAE J1100相同，位置或指定座椅位置由一级后缀决定。

二级后缀用于给出条件或进行说明。

在第4节中有更详细的说明。

为方便查找所需要的信息，增加了一个详细的目录列表。

进行了重大修改的内容如下所述。

在过去，在任何载荷条件下，所有与地面相关的尺寸均与地平面垂直。

对这个定义进行了编辑性修改以澄清这一点。

SAE J1100也重新引入了“EPA-净重”情况，并阐述了在该载荷条件下的特定尺寸。

此外，文件还给出了在生产商声明的车辆总重条件下测量的新尺寸，同时增加了从已被取消了的SAE J689中摘取的尺寸。

Each UNS number consists of a single letter-prefix followed by five digits. In most cases the letter is suggestive of the family of metals identified, for example, A for aluminum, P for precious metals, S for stainless steels. T able 2 shows the secondary division of some primary series of numbers.3.2Whereas some of the digits in certain of the UNS number groups have special assigned meaning, each seriesis independent of the others in such significance; this practice permits greater flexibility and avoids complicated and lengthy UNS numbers.

Forexample: The carbon steel which is presently identified by "AISI 1020" (American Iron & Steel Institute) is covered by "UNS G10200" and the nickel alloy presently identified by "M252" is covered by "UNS N07252." 3.4Welding filler metals fall into two general categories: those whose compositions are determined by the fillermetal analysis (e.g., solid bare wire or rods and cast rods), and those whose composition is determined by the weld deposit analysis (e.g., covered electrodes, flux-cored and other composite wire electrodes). The latter are assigned to a new primary series with the letter W as shown in Table 1. The solid bare wire and rods continue to be assigned in the established number series according to their composition.(Readers are cautioned not to make their own "assignments" of numbers from such listings, as this can result in unintended and unexpected duplication and conflict.)3.5The ASTM and the SAE periodically publish up-to-date listings of all UNS numbers assigned to specific metalsand alloys, with appropriate reference information on each. (See 6.6.) Many trade associations also publish similar listings related to materials of primary interest to their organizations.anization for Administering Unified Numbering System for Metals and Alloys4.1The organization for administering the UNS consists of: (1) an advisory board, (2) several number-assigningoffices, (3) a corps of volunteer consultants, and (4) staffs at ASTM and SAE. In addition, SAE and ASTM committees dealing with various groups of materials may be consulted.4.1.1The Advisory Board has approximately 20 volunteer members who are affiliated with major producing andusing industries, trade associations, government agencies, and standards societies, and who have extensive experience with identification, classification, and specification of materials. The Board is the administrative arm of SAE and ASTM on all matters pertaining to the UNS. It coordinates thinking on the format of each series of numbers and the administration of each by selected experts. It sets up ground rules for determining eligibility of any material for a UNS number, for requesting such numbers, and for appealing unfavorable rulings. It is the final referee on matters of disagreement between requesters and assigners.4.1.2UNS number assigners for certain materials are set up at trade associations which have successfullyadministered their own numbering systems; for other materials, assigners are located at the offices of SAE and ASTM. Each of these assigners has the responsibility for administering a specific series of numbers, as shown in T able 3. Each considers requests for assignment of new UNS numbers, and informs applicants of the action taken. Trade association UNS number assigners also report immediately to both SAE and ASTM details of each number assignment. ASTM and SAE assigners collaborate with designated consultants when considering requests for assignment of new numbers.4.1.3Consultants are selected by the Advisory Board to provide expert knowledge of a specific field of materials.Since they are utilized primarily by the Board and the SAE and ASTM number assigners, they are not listed in this document. At the request of the ASTM or SAE number assigner, a consultant considers a request fora new number in light of the ground rules established for the material involved, decides whether a newnumber is justified, and informs the ASTM or SAE number assigner accordingly.This utilization of experts (consultants and number assigners) is intended to insure prompt and fair consideration of all requests. It permits each decision to be based on current knowledge of the needs of a specific industry of producers and users.TABLE 3—NUMBER ASSIGNERS AND AREAS OF RESPONSIBILITYThe Aluminum Association Aluminum and aluminum alloys900 19th Street, NW, Suite 30UNS Number Series: A00001-A99999 Washington, DC 20006Telephone: (202) 862-5100American Society for T esting and Materials Rare earth and rare earth-like metals and alloys 100 Barr Harbor Drive UNS Number Series: E00001-E99999West Conshohocken, P A 19428-2959Attention: Office for Unified Numbering System for Metals Cast ironsTelephone: (215) 299-5400UNS Number Series: F00001-F99999Cast steelsUNS Number Series: J00001-J99999Miscellaneous steels and ferrous alloysUNS Number Series: K00001-K99999Low melting metals and alloysUNS Number Series: L00001-L99999Miscellaneous nonferrous metals and alloysUNS Number Series: M00001-M99999Precious metals and alloysUNS Number Series: P00001-P99999American Welding Society Welding filler metals550 N.W.

(See 6.4.)5.3For a new UNS number to be assigned, the composition (or other properties, as applicable) must besignificantly different from those of any metal or alloy which has already been assigned a UNS number.5.3.1In the case of metals or alloys that are normally identified or specified by chemical composition, the chemicalcomposition limits must be reported.5.3.2In the case of metals or alloys which are normally identified or specified by mechanical (or other) properties,such properties and limits thereof must be reported. Only those chemical elements and limits, if any, which are significant in defining such materials need be reported.5.4Requests for new numbers shall be submitted on "Application for UNS Number Assignment" forms (Figure 1).Copies of these are available from any UNS number assigning office (Table 3) or facsimiles may be made of the one herein.5.5All instructions on the printed application form should be read carefully and all information provided asindicated. (See 6.5.)5.6To further assist in assigning UNS numbers, the requester is encouraged to suggest a possible UNS number ineach request, giving appropriate consideration to any existing number presently used by a trade association, standards society, producer, or user.5.7Each completed application form shall be sent to the UNS number assigning office having responsibility for theseries of numbers which appears to most closely relate to the material described on the form (Table 3).FIGURE 1A—APPLICATION FORM FOR UNS NUMBER ASIGNMENT (FRONT)FIGURE 1B—APPLICATION FORM FOR UNS NUMBER ASSIGNMENT (BACK)6.Notes6.1The terms "commercial standing," "production usage," and others, are intended to portray a material in activeindustrial use, although the actual amount of such use will depend, among other things, upon the type of materials. (Obviously gold will not be used in the same "tonnages" as hot rolled steel.)Different standardizing groups use different criteria to define the status that a material has to attain before a standard number will be assigned to it. For instance, the American Iron and Steel Institute requires for stainless steels "two or more producers with combined production of 200 tons per year for at least two years";the Copper Development Association requires that the material be "in commercial use (without tonnage limits)"; the Aluminum Association requires that the alloy must be "offered for sale (not necessarily in commercial use)"; the SAE Aerospace Materials Division calls for "repetitive procurement by at least two users."While it is apparent that no hard and fast usage definition can be set up for an all-encompassing system, the UNS numbers are intended to identify metals and alloys that are in more or less regular production and use.A UNS number will not ordinarily be issued for a material which has just been conceived or which is still in onlyexperimental trial.6.2Organizations that issue specifications should report to appropriate UNS number assigning offices (see 4.1.2)any specification changes which affect descriptions shown in published UNS listings.6.3This arrangement of alphanumeric six character numbers is a compromise of the thinking that identificationnumbers should indicate many characteristics of the material, and the thinking that numbers should be short and uncomplicated to be widely accepted and used.6.4In assigning UNS numbers, and consequently in searching complete listings of numbers, the predominantelement of the metal or alloy usually determines the prefix letter of the series to which it is assigned. In certain instances where no one element predominates, arbitrary decisions are made as to what prefix letter to use, depending upon the producing industry and other factors.6.5The application form is designed to serve also as a data input sheet to facilitate processing each requestthrough to final printout of the data on electronic data processing equipment and to minimize transcription errors at number-assigning offices and data processing centers.6.6One such listing is ASTM Publication No. DS-56 and SAE Handbook Supplement HS-1086 (a joint ASTM-SAEpublication).6.7Marginal Indicia—The change bar (l) located in the left margin is for the convenience of the user in locatingareas where technical revisions have been made to the previous issue of the report. An (R) symbol to the left of the document title indicates a complete revision of the report.PREPARED BY THE SAE UNIFIED NUMBERING SYSTEM ADVISORY BOARDRationale—The only change to the document was in Table 3—Copper Development Association’s address changed.Relationship of SAE Standard to ISO Standard—Not applicable.Application—This SAE Recommended Practice describes a unified numbering system (UNS) for metals and alloys which have a "commercial standing" (see 6.1), and covers the procedure by which such numbers are assigned.Section 2 describes the system of alphanumeric designations or "numbers" established for each family of metals and alloys.Section 3 outlines the organization established for administering the system.Section 4 describes the procedure for requesting number assignment to metals and alloys for which UNS numbers have not previously been assigned.The UNS provides a means of correlating many nationally used numbering systems currently administered by societies, trade associations, and individual users and producers of metals and alloys, thereby avoiding confusion caused by use of more than one identification number for the same material;and by the opposite situation of having the same number assigned to two or more entirely different materials. It provides, also, the uniformity necessary for efficient indexing, record keeping, data storage and retrieval, and cross referencing.A UNS number is not in itself a specification, since it establishes no requirements for form, condition,quality, etc. It is a unified identification of metals and alloys for which controlling limits have been established in specifications published elsewhere.

(See SAE J826.)3.26Normal Top of Frame-Truck—The longest normal surface of the top flange of the truck frame within the wheelbase.3.27Cargo Floor—The surface for supporting cargo including ribs, or Undepressed Floor Covering.4.General—The dimensions in this report will enable the measurement of a vehicle as designed. The prefix "A"may precede a dimension taken from a vehicle as built, which will enable a comparison between vehicles as designed and/or built.All dimensions are defined normal to the three-dimensional reference system, described in SAE J182 except for ground-related dimensions which are defined normal to ground with the vehicle loaded to a design load weight, unless defined in the dimension definition.All dimensions are measured to the base vehicle and do not include Regular Production Options (RPO) or accessory parts, unless defined by the dimension definition.The dimensions in this document are classified in groups of relevant interest. Each dimension is assigned a code which is composed of a prefix letter denoting the direction or type of dimension and a number issued in sequence as required by each prefix letter. The code is interpreted as follows:NOTE—# in front of dimension code indicates a change from the previous version of SAE J1100.The prefix letter:W-Width dimensionsH-Height dimensionsPD-Passenger distribution dimensionsL-Length dimensionsS-Surface area dimensionsSD-Seat facing direction dimensionsV-Volume dimensionsPL-Pedal Lengths (sizes & clearances)PW-Pedal Widths (sizes & clearances)PH-Pedal Heights (sizes & clearances)TL-Length dimensions-H-Point Location & TravelTH-Height dimensions- H-Point Location & TravelThe number:1-99Interior dimensions100-199Exterior dimensions200-299Cargo or luggage dimensions300-399Interior dimensions-Unique for Truck and MPV's400-499Exterior dimensions-Unique for Truck and MPV's500-599Cargo Dimensions-Unique for Truck and MPV'sTo assist in locating dimensions in this document, numeric and alphabetic sequences are shown in Sections 15 and 16.4.1Interior Dimensions—All Interior Dimensions are defined with an adjustable front seat in its rearmost normaldriving position, resulting in the Design H-Point being positioned at the Seating Reference Point (SgRP) position. All other adjustable features, such as an adjustable steering wheel and adjustable seat height, a seatback that adjusts independently from the Seat Cushion, power 4-way or 6-way seats, etc., shall be positioned in their normal driving position as specified by the manufacturer. Steering wheel shall be positioned with front wheels in straight-ahead position.All interior dimensions for designated seated positions are defined on the Y-plane centerline of the occupant, unless otherwise defined in the dimensions definition. The H-Point machine and two-dimensional drafting template specified in SAE J826 shall use the 95th percentile leg segments.For heavy-duty trucks, suspension seats will be positioned as specified by the vehicle manufacturer in the normal driving position with any fore and aft isolator locked out.4.2Exterior Dimensions—All exterior dimensions terminate at the outside surface of the sheet metal, bumper, orintegral moldings, unless otherwise specified. The front wheels shall be positioned in the straight-ahead position. All exterior dimensions define the proportional shape of the vehicle, as opposed to its designed pieces.

实用标准文档文案大全机动车辆驾驶员的眼睛位置前言---此被推荐实行的SAE标准介绍了眼椭圆——驾驶员眼睛位置的一种统计表示法，它便于对机动车辆视野进行设计与评估。

眼椭圆的应用包括后视镜尺寸和位置，雨刮及除霜面积，车柱尺寸及位置，以及一般的外部视野。

这些应用在其他SAE标准及ISO标准中有讲解。

这篇眼椭圆修订本是SAE J941自编制以来最有意义的一次修订。

新的眼椭圆与旧的眼椭圆不同之处有以下几个方面：a.俯视图和后视图中椭圆轴线与汽车轴线平行。

b.侧视图中X轴的角度在前部向下倾斜角更大。

c.95%（99%）的眼椭圆：1．x轴增长了7.5（18.9）mm2．Y轴减短了44.6（63.6）mm3．Z轴增长了7.4（10.1）mm。

d.眼椭圆中心定位在更高，更向后的位置。

e.侧视图中眼椭圆中心位置是由一些参数（SgRP, 转向轮位置，座椅坐垫角度，及有无离合器踏板）组成的函数式确定。

f.眼椭圆不再根据驾驶员座椅靠背角来确定。

g.座椅前后行程小于133mm时的眼椭圆x轴长度与先前SAE J941中是一样的。

Y轴、z轴及眼椭圆中心的位置，则是依据本文中所给出的新的方程式来确定。

h.P点和E点的位置是根据俯视图中到后视镜及A柱的视野线来确定，但要根据新的眼椭圆形状和位置进行调整。

新增内容及附录，总结如下：a.美国人群按男女等比例混合后95%及99%人群在固定座椅情况下的眼椭圆（附录B）。

b.身高和性别按任何比例混合后的人群，在可调座椅和固定座椅下的眼椭圆的绘制步骤（附录A和C）。

c.切线眼椭圆与inclusive眼椭圆的对比图表。

可用这些图表信息来创建inclusive眼椭圆（附录D）B类车辆的眼椭圆和以前的 SAE J941是一样的（附录E）。

附录仅仅提供信息，并不是本文的标准化要求。

套管隔热的热效率测量标准1 范围该程序是测量套管材料对辐射热源的热效率。

套管的热效率（S E）是通过在指定的温度和指定的位置和距离（相对辐射热源）测量光滑黑色的单径陶瓷棒（有或者没有标准直径的套管两种状态）的表面温度的区别来确定的。

1.1 安全性这种方法可能涉及危险的物质，操作和设备。

美国汽车工程师学会（SAE）的标准并没有提出解决其与使用相关的安全问题。

本文档的使用者在使用之前有责任查阅并建立合适的安全与健康条例和确定规章使用范围。

1.2 局限性该方法测量的温度范围是从121°C -482°C。

套管的尺寸大小仅限于内径：19mm，长：30cm±2cm 。

测试距离是从辐射热源表面到陶瓷棒表面的最短测量跨度。

除非另有规定，标准距离是指陶瓷棒平行于热源正上方并距离其25mm±2mm。

测试是在无风和没有震动的条件下执行的。

不要将温度序列作为一个热循环使用。

1.3 这个测试方法是基于国标标准单位。

1.4 使用者注意：当引用本文件时，使用合适的字母代码来指定温度条件（表1），序列（表2），烟气生成选项（见6.3.2）和样品位置（见6.3.3）。

例如，在SAE文件号码后的一行代码B（2）S（25）P（3）D（20）的意思是：按照序列2的条件加热，先加热到121°C，然后再加热到260°C，测量烟气生成（S）时间不超过25s。

样品的放置位置（P）是在3点钟位置，距离热源20mm（D）。

把数字放在括号里。
