ASME压力容器及其有限元分析压力容器,英文:pressure vessel,是指盛装气体或者液体,承载一定压力的密闭设备。
贮运容器、反应容器、换热容器和分离容器均属压力容器。
压力容器的用途十分广泛。
它是在石油化学工业、能源工业、科研和军工等国民经济的各个部门都起着重要作用的设备。
压力容器一般由筒体、封头、法兰、密封元件、开孔和接管、支座等六大部分构成容器本体。
此外,还配有安全装置、表计及完全不同生产工艺作用的内件。
压力容器由于密封、承压及介质等原因,容易发生爆炸、燃烧起火而危及人员、设备和财产的安全及污染环境的事故。
ASME压力容器设计意味着计算方法是按ASME第8卷中的规则和计算方法进行设计和计算,不一定要选用ASME材料,除非和客户签订的技术协议里特别注明需要使用ASME材料,容器的管路当然也是要按ASME的要求。
由于产品的安全性和经济性的要求,有限元分析应用需求是最广泛的。
根据标准的要求,设计者可以借助有限元来解决容器的结构强度、稳定性及寿命(疲劳)的设计问题。
压力容器的主要特点结构形式:压力容器主要的结构形式为回转壳,当然最典型的是柱壳(常称为筒体)和球壳(球罐和封头等)。
常见的结构主要特点是:开孔、支撑、加强构件等;壳体的厚度远小于壳体的曲率半径;结构不规则;异种材料连接等。
根据其结构形式的主要特点和用途还可以进一部分类为:塔式容器、卧式容器、换热器、球罐等。
载荷形式:1) 压力:这是最重要的载荷形式,包括内压和外压;2) 热载荷:主要是由于温度梯度引起来的热应力;3) 力和力矩:设备管道传给设备的外力,附加载荷等4) 地震:设备的地震也是必须考虑的问题;5) 风载荷:对于一些塔式容器和球罐,风载荷也是主要考虑的载荷;6) 雪载荷:对我国北方地区的室外容器;求解模式:静力,动力,屈曲,疲劳,线弹性,弹塑性,非线性,接触等压力容器的分类一、按设计压力分类:1、低压(L)0.1MPa≤P<1.6 MPa2、中压(M)1.6 MPa≤P<10 MPa3、高压(H)10 MPa≤P<100 MPa4、超高压(U)P≥100 MPa二、按工艺过程中的作用分:1、反应压力容器(R):主要是用于完成介质的物理、化学反应的压力容器。

Principle of Operation:The Zipper closure was developed for AE’s Zipperclave ® quick-opening, low pressure vessels. Closure is effected by a resilient spring member (the “Zipper”) inserted through a circumferential groove in the body and cover. Simply release the safety sleeve and pull the Zipper to remove the cover. A quick release/safety lock and cover safety device are provided to ensure that the spring is fully inserted.ZipperClave ®Pressure VesselVolume: 500 mlVessel MAWP*: 2,200 psi @ 450ºF (151 bar @ 232ºC)Material of Construction: 316 Stainless Steel or all wetted parts* Maximum Allowable Working PressureGeneral Specifications:WARNINGFAILURE, IMPROPER SELECTION OR IMPROPER USE OF THE PRODUCTS AND/OR SYSTEMS DESCRIBED HEREIN OR RELATED ITEMS CAN CAUSE DEATH, PERSONAL INJURY AND PROPERTY DAMAGE .This document and other information from Parker Hannifin Corporation, its subsidiaries and authorized distributors provide product and/or system options for further investigation by users having technical expertise.

压力容器规范标准目的:确保压力容器在设计寿命内安全运行内容:材料、设计、制造、检验等性质:法规,必须遵守特点:定期补充、修改,用新规范1.3.1国外主要规范标准简介:美国ASME规范、日本压力容器标准、欧盟压力容器标准1、美国ASME规范目前ASME规范共有十二卷包括锅炉、压力容器、核动力装置、焊接、材料、无损检测等内容。
ASME规范每三年出版一个新的版本,每年有两次增补。
在形式上,ASME规范分为4个层次:规范(Code)、规范案例(Code Case)、条款解释(Interpretation)、规范增补(Addenda)ASME规范中与压力容器设计有关的主要是第Ⅷ篇《压力容器》、第Ⅶ篇《移动式容器建造和连续使用规则》和第Ⅹ篇《玻璃纤维增强塑料压力容器》。
第Ⅷ篇分为3个册:第1册《压力容器》第2册《压力容器——另一规则》第3册《高压容器另一规则》简称ASMEⅧ-1、ASMEⅧ-2和ASMEⅧ-3ASMEⅧ-1ASMEⅧ-1为常规设计标准,适用压力小于等于20MPa;它以弹性失效设计准则为依据,根据经验确定材料的许用应力,并对零部件尺寸作出一些具体规定。
由于它具有较强的经验性,故许用应力较低。
ASMEⅧ-1不包括疲劳设计,但包括静载下进入高温蠕变范围的容器设计。
ASMEⅧ-2ASMEⅧ-2为分析设计标准,它要求对压力容器各区域的应力进行详细地分析,并根据应力对容器失效的危害程度进行应力分类,再按不同的安全准则分别予以限制。
跟ASMEⅧ-1相比,ASMEⅧ-2对结构的规定更细,对材料、设计、制造、检验和验收的要求更高,允许采用较高的许用应力,所设计出的容器壁厚较薄。
ASMEⅧ-2包括了疲劳设计,但设计温度限制在蠕变温度以内。
ASMEⅧ-3ASMEⅧ-3主要适用于设计压力不小于70MPa的高压容器。
它不仅要求对压力容器各区域的应力进行详细地分析和分类评定,而且要做疲劳分析或断裂力学评定,是目前为止要求最高的压力容器规范。

Introduction
介绍 A good deal of the Mechanics of Materials can be introduced entirely within the confines of uniaxially stressed structural elements, and this was the goal of the previous modules. 在单向的压力结构元素范围内,大量的材料力学可以被使用。这也是较早的模块目标。 But of course the real world is three-dimensional, and we need to extend these concepts accordingly. 但是当然,真正的世界是三维的。因此我们需要去增加这些概念。 We now take the next step, and consider those structures in which the loading is still simple, but where the stresses and strains now require a second dimension for their description. 我们现在开始下一步,考虑这些载荷的中的结构依然很简单。但是压力和拉应力现在需要一个二维描述。 Both for their value in demonstrating two-dimensional effects and also for their practical use in mechanical design, we turn to a slightly more complicated structural type: the thin-walled pressure vessel. 对于他们在二维演示中的效果和在机械实际中使用的实用性,我们转变成一个一个稍微复杂点的结构类型;包庇压力容器。 Structures such as pipes or bottles capable of holding internal pressure have been very important in the history of science and technology. 像支持内部压力的管线或者钢瓶结构在科学技术的历史上已经很重要了。 Although the ancient Romans had developed 内蒙古工业大学本科生毕业设计说明书 2 municipal engineering to a high order in many ways, the very need for their impressive system of large aqueducts for carrying water was due to their not yet having pipes that could maintain internal pressure. 尽管古罗马已经使用很多方法把市政工程发展到了很高的程度。对于这个令人影响深刻的系统需要大型取水的渡槽是因为他们没有能承受内部压力的管子。 Water can flow uphill when driven by the hydraulic pressure of the reservoir at a higher elevation, but without a pressure-containing pipe an aqueduct must be constructed 在更高海拔水库的液压的驱动下水能艰难流动。但是没有一个能承压的管,一个水槽必须修建。 so the water can run downhill all the way from the reservoir to the destination. 所以水能从书库各个方向流向目的地。
Airplane cabins are another familiar example of pressure-containing structures. They illustrate very dramatically the importance of proper design, since the atmosphere in the cabin has enough energy associated with its relative pressurization compared to the thin air outside that catastrophic crack growth is a real possibility. 飞机的客舱是另一个承受压力结构的相似例子。它戏剧性的解释了合适设计的重要性。因为客舱内有足够消耗的空气同时外部有相对增压的稀薄气体。这就导致了灾难性断裂的发生。 A number of fatal commercial tragedies have resulted from this, particularly famous ones being the Comet aircraft that disintegrated in flight in the 1950’s1 and the loss of a 5-meter section of the roof in the first-class section of an Aloha Airlines B737 in April 19882
大量致命的悲剧都由此导致。尤其在五十年代著名的是彗星飞机在飞行中分解,和在1988年一辆阿罗哈飞机头等舱外壳五米长的割裂。
In the sections to follow, we will outline the means of determining stresses and deformations in structures such as these, since this is a vital first step in designing against failure. 接下来的版块,我们将概述确定这些结构的盈利和形变,因为这是避免错误设计的至关重要的一步。
Stresses
应力 内蒙古工业大学本科生毕业设计说明书 3 In two dimensions, the state of stress at a point is conveniently illustrated by drawing four perpendicular lines that we can view as representing four adjacent planes of atoms taken from an arbitrary position within the material. 在二维中,在一点的应力是很容易被通过话四个垂直的点的图所表示的,那样我们可以认为是代表在材料范围内来自任意一个位置面的四个相邻原子面。 The planes on this “stress square” shown in Fig. 1 can be identified by the orientations of their normals; the upper horizontal plane is a +y plane, since

its normal points in the +y direction. The vertical plane on the right is a +x plane. 显示在图1中正方形的那个面可以用它的法线方向确定。这个上水平的面市一个正Y方向的面,因为它的正位点在y方向。这个右边的垂直面是一个正X面。 Similarly, the left vertical and lower horizontal planes are −y and −x, respectively 相似的,这个左边垂直面和下面的水平面分别是-y和-x。. Figure 1: State of stress in two dimensions: the stress square. 图1;在二尾中应力的显示;压力的平方 The sign convention in common use regards tensile stresses as positive and compressive stresses as negative. 通常使用的标记规定是把拉应力规定为正,把压应力规定为负。 A positive tensile stress acting in the x direction is drawn on the +x face as an arrow pointed in the +x direction. But for the stress square to be in equilibrium, this arrow must be balanced by another acting on the −x face and pointed in the −x direction. 一个正的拉应力用一个x方向箭头表示在x面的x方向。但是对于处在平衡的压力方,这个箭头必须通过另一个显示在-x面和指出在-x面来平衡。 Of course, these are not two separate stresses, but simply indicate the stress state is one of uniaxial tension. 当然,这些不是两个分开的应力。但是简单的表示了压力的表示是一个单轴的张力。 A positive stress is therefore indicated by a + arrow on a + face, or a − arrow on a − face. 一个正压力因此被一个在正面的正箭头或者是在一个负面的负箭头所表示。 Compressive stresses are the reverse: a − arrow on a + face or a + arrow on a − face. 压应力是相反的,一个负箭头在正面或者一个正箭头在负面。
