一、卧式容器的计算方法卧式容器的设计,除按常规计算筒体、封头外,还应验算支座处的局部应力。此局部应力由于它的作用范围比较大,还不能都应用英国标准BS5500(1983年版)的附录G.2(或WRC107会刊)所推荐的局部应力计算方法。支座处的局部应力的计算方法,在很大程度上取决于支座的结构型式。众所周知,支座型式大致可分为三种:鞍式支座、圈座和支腿式支座。石油、化工装置中的卧式容器多置于两个鞍式支座上。对于鞍式支座支承的卧式容器,看起来受力简单,但山于容器重量和支座反力所引起的局部应力的计算还是很复杂的。目前,关于鞍式支座支承的卧式容器的局部应力的计算方
First, the calculation method of horizontal container Horizontal container design, in addition to conventional calculation cylinder, head, but also checking the local stress at the support. This local stress due to its scope of action is relatively large, but also can not be applied British Standard BS5500 (1983 edition) Appendix G.2 (or WRC107 Journal) recommended local stress calculation method. The method of calculating the local stress at the support depends to a large extent on the structure of the support. As we all know, bearing type can be divided into three types: saddle bearing, ring seat and leg bearing. Oil and chemical equipment in the horizontal container placed in more than two saddle bearings. For a horizontal container supported by a saddle, it seems that the force is simple, but the calculation of the local stress caused by the mountain weight in the container and the reaction force of the cradle is still very complicated. At present, the calculation of the local stress of the horizontal container supported by the saddle support
