Dump Truck Overview
Compartment is equipped with automatic devices for dumping cars. Also known as dump trucks, construction vehicles, from motor vehicle chassis, hydraulic lifting mechanism, taking the composition of power devices andFreight platform.
In civil engineering, often with the excavators, loaders, belt conveyors, such as joint operations, constitute a loading, transportation and unloading production lines, to carry out earthworks, gravel, loading and unloading loose materials transport. Compartment can be loaded automatically as a result of a certain tipping point of discharge, discharge significant savings of time and labor, reduce the transport cycle, increase productivity, reduce transportation costs, and to identify the loading capacity. Transport machinery is commonly used.
Engine, chassis and cab of the truck the same structure and general. Can train to the tipping or lateral tipping, through manipulation of the system control rod movement, tipping beyond the more common to promote the piston rod so that tipping inside. A small number of two-way tipping. The allocation of oil by high-pressure valves, tubing into the lifting hydraulic cylinder, inside the front fenders have a driver's safety. Engine through the transmission, hydraulic pump driven from power devices, hydraulic tipping body inside fuel tanks, hydraulic pumps, distribution valves, hydraulic lifting cylinder, control valves and tubing and other components. Hydraulic tipping body inside the tank, pump, distribution valves, hydraulic lifting cylinder, control valves and tubing and other components. Engine through the transmission, hydraulic pump driven from power plant, high pressure oil through the distribution valve, hydraulic cylinder tubing into the lift, push rod so that tipping inside. After tipping more to the common piston rod through the control system to control movement, will enable the train to stop at any position on the need for the tilt. Compartments use of its own gravity and hydraulic control reset.
Dump Truck of the main technical parameters are loaded with weight, and marked volume loading. New car or car repair factory commissioning must be carried out so that the
process inside a smooth lifting action without strings. Use of the site shall be the right choice of lubricating oil, saving unloading time and labor, the attention of lubrication cycle, lifting oil change schedule strictly. Shipment according to nominal load, overloading is strictly prohibited.
Dump truck classification:
1. In accordance with the carrying capacity of the chassis can be divided into series dump truck, dump in tons of series and series of large-tonnage Dump;
2. By the driver dump the form of the bridge can be divided into single-, double-bridge dump, dump eight after the first four, the first four series of ten different models;
3. By unloading the hydraulic lifting mechanism can be divided into different Monacrosporium biparietal dump and dump.
Structural analysis of the dump truck:
Mainly by the hydraulic dump truck dump bodies, cars, and its annexes constitute the frame. Hydraulic dump them inside the structure of institutions and manufacturers in various different modifications, the following compartments and the lifting mechanism in accordance with the pattern of the two aspects of the structure of that dump truck.
1、compartment type
Node compartments by use of different body types can be broadly divided into: general rectangular bucket compartment and inside mine.
Ordinary rectangular compartments for the carriage of goods in bulk. Plate with subsequent automatic opening and closing of institutions, to ensure smooth unloading of goods. Ordinary rectangular compartment thickness as follows: pre-board 4 to 6mm, side panels 4 to 8 mm, after the board 5 to 8 mm, bottom 6 to 12 mm. For example: dump truck license ChengLi common standard rectangular compartment thickness as follows: 4 at the end of the first 4 side 8 5.
Inside bucket mining is applicable to a larger particle size, such as large stones of goods in transit. Taking into account the impact of goods and touch buildings, mining bucket inside the design of more complex shape, with thicker material. For example:-way power bucket mining dump truck license compartment standard thickness as follows: 6 at the end of the first 6 edges 10, and some models in the floor on some angle iron welded to increase the train capacity of stiffness and impact resistance.
2 、lifting body type
Dump truck lifting mechanism is the core of the primary advantages and disadvantages of discriminant indicators truck.
Type lifting mechanism common current: F-type lifting mechanism to enlarge tripod, T-style tripod lifting mechanism to enlarge, double lift, the former top-lift and double rollover.
Enlarge tripod-type lifting mechanism is currently the most frequently used means of a lift for 8 to 40 tons of dead weight, train length of 4.4 ~ 6 meters. Advantage of the structure of mature, stable lifting and cheap; disadvantages inside the frame on the main floor of the closed height of the larger plane.
Most forms of double lift truck in 6X4, it is in the second on both sides of the bridge in front of more than one level of the tank is installed (usually 3 ~ 4), the hydraulic cylinder on the fulcrum of a direct role in the compartment floor. Double advantage of lifting the main floor for the inside frame of the closing high on a smaller plane; the shortcomings of the hydraulic system is very difficult to ensure synchronization of two hydraulic cylinders, give less smooth Health on the inside bottom of the overall stiffness higher.
Lift the top way before the simple structure, inside the frame on the main floor of the closed high plane can be very small, vehicle stability, the smaller the hydraulic system pressure, but the first trip at the most larger-cylinder class, the high cost .
Double-sided cylinder roll force is better, less travel to achieve double-rollover; but more complex hydraulic piping, Health cited a higher rate of roll-over accident.
Dump Truck Selection:
Dump Truck with the development and improvement of domestic purchasing power, dump truck is not in the traditional sense, what the living can do everything dump truck, from the design point of view is different goods, different working conditions, the development of different regions of different products. This requires users to buy vehicles specific to the use of manufacturers.
1、chassis
In the selection of the chassis, the economic benefits that are to be considered, such as: the price of the chassis, loading quality, overloading the capacity of 100 kilometers fuel consumption, maintenance fee, etc.. In addition, users should also consider the following chassis parameters:
① plane height on the chassis frame. General 6x4 chassis frame height on the plane for the 1050 ~ 1200. The higher the value the greater the vehicle center of gravity, the more
easily overturned. Factors affecting the value is the tire diameter, suspension of the layout and height of the main frame section.
②chassis rear overhang. The numerical impact of the General Assembly of Health cited the stability of dump truck, resulting in roll-over accident of Health cited. This value is normally between 500-1100 (except truck rollover).
③ vehicle reasonable match, use and reliable.
2、upload
Dump Truck manufacturer modified the current cohabitation, choose the selection of dump truck manufacturers is equally important than the choice of products. In addition to look at products, but also the ability of equipment manufacturers, dump truck load of design, whether it is a mature technology and equipment, after-sales service commitment, whether or not to buy such accessories.

自卸车概述
车厢配有自动倾卸装置的汽车。又称为翻斗车、工程车，由汽车底盘、液压举升机构、取力装置和货厢组成。
在土木工程中，常同挖掘机、装载机、带式输送机等联合作业，构成装、运、卸生产线，进行土方、砂石、松散物料的装卸运输。由于装载车厢能自动倾翻一定角度卸料，大大节省卸料时间和劳动力，缩短运输周期，提高生产效率，降低运输成本，并标明装载容积。是常用的运输机械。
发动机、底盘及驾驶室的构造和一般载重汽车相同。车厢可以后向倾翻或侧向倾翻，通过操纵系统控制活塞杆运动，以后向倾翻较普遍，推动活塞杆使车厢倾翻。少数双向倾翻。高压油经分配阀、油管进入举升液压缸，车厢前端有驾驶室安全防护板。发动机通过变速器、取力装置驱动液压泵，车厢液压倾翻机构由油箱、液压泵、分配阀、举升液压缸、控制阀和油管等组成。车厢液压倾翻机构由油箱、液压泵、分配阀、举升液压缸、控制阀和油管等组成。发动机通过变速器、取力装置驱动液压泵，高压油经分配阀、油管进入举升液压缸，推动活塞杆使车厢倾翻。以后向倾翻较普遍，通过操纵系统控制活塞杆运动，可使车厢停止在任何需要的倾斜位置上。车厢利用自身重力和液压控制复位。
自卸车的主要技术参数是装载重量，并标明装载容积。新车或大修出厂车必须进行试运转，使车厢举升过程平稳无串动。使用时各部位应按规定正确选用润滑油，大大节省卸料时间和劳动力，注意润滑周期，举升机构严格按期调换油料。按额定装载量装运，严禁超载。
自卸车的分类：
1.按底盘承载能力可分为轻卡系列自卸、中吨系列自卸和大吨位系列自卸；
2.按驱动形式可分单桥自卸、双桥自卸、前四后八自卸、前四后十等不同系列车型；
3.按卸载液压举升机构不同可分为单顶自卸和双顶自卸。
自卸车的构造分析：
自卸车主要由液压倾卸机构、车厢、车架及其附件构成。其中液压倾卸机构和车厢结构各个改装厂家不尽相同，以下按车厢和举升机构的型式两个方面说明自卸车的结构。
1、车厢型式
车厢结机构型式按用途不同大概可分为：普通矩形车厢和矿用铲斗车厢。普通矩形车厢用于散装货物运输。其后板装有自动开合机构，保证货物顺利卸出。普通矩形车厢板厚为：前板4到6mm，边板4到8 mm，后板5到8 mm，底板6到12 mm。比如：程力牌自卸车普通矩形车厢标准配置板厚为：前4边4底8后5。
矿用铲斗车厢则适用于大石块等粒度较大货物的运输。考虑到货物的冲击和碰幢，矿用铲斗车厢的设计形状较复杂，用料较厚。比如：程力牌自卸车矿用铲斗车厢标准配置板厚为：前6边6底10，而且有些车型在底板上焊接一些角钢，以增加车厢的刚度和抗冲击能力。
2 举升机构型式
举升机构是自卸车的核心，是判别自卸车优劣的首要指标。举升机构的型式目前国内常见的有：F式三角架放大举升机构、T式三角架放大举升机构、双缸举升、前顶举升和双面侧翻。
三角架放大式举升机构是目前国内使用最多的一种举升方式，适用载重量8~40吨，车厢长度4.4~6米。优点为结构成熟、举升平稳、造价低；缺点为车厢底板与主车架上平面的闭合高度较大。
双缸举升形式大多用在6X4自卸车上，是在第二桥前方两侧各安装一支多级缸（一般为3~4级），液压缸上支点直接作用在车厢底板上。双缸举升的优点为车厢底板与主车架上平面的闭合高度较小；缺点是液压系统很难保证两液压缸同步，举生平稳性较差，对车厢底板的整体刚度要求较高。
前顶举升方式结构简单、车厢底板与主车架上平面的闭合高度可以很小，整车稳定性好，液压系统压力较小，但前顶多级缸行程较大，造价很高。
双面侧翻液压缸受力较好，行程较小，可实现双面侧翻；但液压管路较复杂，举生翻车事故发生率较高。
自卸车选型：
随着自卸汽车的发展和国内购买能力的提高，自卸车已经不是传统意义上的什么活都可以干的万能自卸车，从设计角度讲也是按不同的货物、不同工况、不同地区开发不同的产品。这就要求用户在购买车辆时要向厂家提供具体使用情况。
1、底盘
在选择底盘时，一般是按经济效益来考虑的，比如：底盘的价格、装载质量、超载能力、百公里油耗、养路费等。除此之外，用户还要考虑底盘的如下参数：
①底盘车架上平面离地高度。一般6x4底盘车架上平面离地高度为1050~1200。
该数值越大整车重心越高，越容易造成翻车。影响该数值的因素主要是轮胎直径、悬挂的布置和主车架截面高度。
②底盘后悬。该数值过大会影响自卸车举生稳定性，造成举生翻车事故。此数值一般在500-1100之间（侧翻自卸车除外）。
③整车匹配合理、使用可靠。
2、上装
目前自卸车改装厂家鱼龙混杂，选择自卸车时选择厂家比选择产品同样重要。除看产品外，还要了解厂家的设备能力、自卸车上装的设计、工艺装备是否成熟、售后服务承诺、配件是否能买到等。

Component-based Safety Computer of Railway Signal Interlocking System 1 Introduction Signal Interlocking System is the critical equipment which can guarantee traffic safety and enhance operational efficiency in railway transportation. For a long time, the core control computer adopts in interlocking system is the special customized high-grade safety computer, for example, the SIMIS of Siemens, the EI32 of Nippon Signal, and so on. Along with the rapid development of electronic technology, the customized safety computer is facing severe challenges, for instance, the high development costs, poor usability, weak expansibility and slow technology update. To overcome the flaws of the high-grade special customized computer, the U.S. Department of Defense has put forward the concept：we should adopt commercial standards to replace military norms and standards for meeting consumers’demand [1]. In the meantime, there are several explorations and practices about adopting open system architecture in avionics. The United Stated and Europe have do much research about utilizing cost-effective fault-tolerant computer to replace the dedicated computer in aerospace and other safety-critical fields. In recent years, it is gradually becoming a new trend that the utilization of standardized components in aerospace, industry, transportation and other safety-critical fields. 2 Railways signal interlocking system 2.1 Functions of signal interlocking system The basic function of signal interlocking system is to protect train safety by controlling signal equipments, such as switch points, signals and track units in a station, and it handles routes via a certain interlocking regulation. Since the birth of the railway transportation, signal interlocking system has gone through manual signal, mechanical signal, relay-based interlocking, and the modern computer-based Interlocking System. 2.2 Architecture of signal interlocking system Generally, the Interlocking System has a hierarchical structure. According to the function of equipments, the system can be divided to the function of equipments; the system

附件1：外文资料翻译译文 抗侧向荷载的结构体系 常用的结构体系 若已测出荷载量达数千万磅重，那么在高层建筑设计中就没有多少可以进行极其复杂的构思余地了。确实，较好的高层建筑普遍具有构思简单、表现明晰的特点。 这并不是说没有进行宏观构思的余地。实际上，正是因为有了这种宏观的构思，新奇的高层建筑体系才得以发展，可能更重要的是：几年以前才出现的一些新概念在今天的技术中已经变得平常了。 如果忽略一些与建筑材料密切相关的概念不谈，高层建筑里最为常用的结构体系便可分为如下几类： 1.抗弯矩框架。 2.支撑框架，包括偏心支撑框架。 3.剪力墙，包括钢板剪力墙。 4.筒中框架。 5.筒中筒结构。 6.核心交互结构。 7. 框格体系或束筒体系。 特别是由于最近趋向于更复杂的建筑形式，同时也需要增加刚度以抵抗几力和地震力，大多数高层建筑都具有由框架、支撑构架、剪力墙和相关体系相结合而构成的体系。而且，就较高的建筑物而言，大多数都是由交互式构件组成三维陈列。 将这些构件结合起来的方法正是高层建筑设计方法的本质。其结合方式需要在考虑环境、功能和费用后再发展，以便提供促使建筑发展达到新高度的有效结构。这并
不是说富于想象力的结构设计就能够创造出伟大建筑。正相反，有许多例优美的建筑仅得到结构工程师适当的支持就被创造出来了，然而，如果没有天赋甚厚的建筑师的创造力的指导，那么，得以发展的就只能是好的结构，并非是伟大的建筑。无论如何，要想创造出高层建筑真正非凡的设计，两者都需要最好的。 虽然在文献中通常可以见到有关这七种体系的全面性讨论，但是在这里还值得进一步讨论。设计方法的本质贯穿于整个讨论。设计方法的本质贯穿于整个讨论中。 抗弯矩框架 抗弯矩框架也许是低，中高度的建筑中常用的体系，它具有线性水平构件和垂直构件在接头处基本刚接之特点。这种框架用作独立的体系，或者和其他体系结合起来使用，以便提供所需要水平荷载抵抗力。对于较高的高层建筑，可能会发现该本系不宜作为独立体系，这是因为在侧向力的作用下难以调动足够的刚度。 我们可以利用STRESS，STRUDL 或者其他大量合适的计算机程序进行结构分析。所谓的门架法分析或悬臂法分析在当今的技术中无一席之地，由于柱梁节点固有柔性，并且由于初步设计应该力求突出体系的弱点，所以在初析中使用框架的中心距尺寸设计是司空惯的。当然，在设计的后期阶段，实际地评价结点的变形很有必要。 支撑框架 支撑框架实际上刚度比抗弯矩框架强，在高层建筑中也得到更广泛的应用。这种体系以其结点处铰接或则接的线性水平构件、垂直构件和斜撑构件而具特色，它通常与其他体系共同用于较高的建筑，并且作为一种独立的体系用在低、中高度的建筑中。

Introduction Friction stir welding (FSW) is a new solid-state welding method developed by The Welding Institute (TWI) in 1991 [1]. The weld is formed by the excessive deformation of the material at temperatures below its melting point, thus the method is a solid state joining technique. There is no melting of the material, so FSW has several advantages over the commonly used fusion welding techniques [2-10]. 1.导言摩擦搅拌焊接（FSW）是焊接学？会于1991年研发的一种新型固态焊接方法。这种焊接？是由材料在低于其熔点的温度上过量变形形成，因此此技术是一种固态连接技术。材料不熔化，所以FSW 相比常用的熔化焊接技术有若干优势。例如，在焊接区无多孔性或破裂，工件（尤其薄板上）没有严重扭曲，并且在连接过程中不需要填料、保护气及昂贵的焊接准备there is no significant distortion of the workpieces (particularly in thin plates), and there is no need for filler materials, shielding gases and costly weld preparation during this joining process. FSW被认为是对若干材料例如铝合金、镁合金、黄铜、钛合金及钢最显著且最有潜在用途的焊接技术FSW is considered to be the most remarkable and potentially useful welding technique for several materials, such as Al-alloys, Mg-alloys, brasses, Ti-alloys, and steels [1-16]. 然而，在FSW过程中，用不合适的焊接参数能引起连接处失效，并且使FSW连接处的力学性能恶化。However, during FSW process using inappropriate welding parameters can cause defects in the joint and deteriorate the mechanical properties of the FSW joints [2, 3]. 此技术起初就主要是为低熔点材料如铝合金、镁合金及铜合金而广泛研究的。The technique has initially been widely investigated for mostly low melting materials, such as Al, Mg and Cu alloys. 此技术已被证明是很有用的，尤其在连接用于航空航天用途的如高合金2XXX及7XXX系列铝合金等难熔高强度的铝合金。It has proven to be very useful, particularly in the joining of the difficult-to-fusion join high strength Al-alloys used in aerospace applications, such as highly alloyed 2XXX and 7XXX series aluminium alloys. 做出Al-5086 H32型板摩擦搅拌对焊的高强度、抗疲劳及断裂的力学性能？。The difficulty of making high-strength, fatigue and fracture resistant Mechanical properties of friction stir butt-welded Al-5086 H32 plate G. .am a,*, S.
