本文分析表明:按《设计规定》1985年版设计卧式容器时,最佳支承位置应为A=0.5 R_i。此时,若容器的直径较小,D_i≤1m;或长度较短,L<3m,或设计压力较高,P≥1.4MPa时均可不必进行简体局部应力校核,只要按标准~[2]选取支座就行。一、寻优程序卧式容器(不考虑设置加强圈)与支承位置A值有关的筒体局部应力共有8个;轴向应力σ_1,σ_2,σ_3,σ_4,剪应力τ,τ_H,鞍座处简体的周向应力σ5、σ6(当考虑垫板加强作用
The analysis of this paper shows that the best support position should be A = 0.5 R_i when designing the horizontal container according to the 1985 edition of “Design Rules”. In this case, if the diameter of the container is small, D_i≤1m; or the length is short, L <3m, or the design pressure is higher, P> 1.4MPa may not need simplified local stress checking, Select the support on the line. First, the optimization procedures Horizontal containers (not to consider the strengthening ring) A value related to the bearing position of the cylinder with a total of eight local stress; axial stress σ_1, σ_2, σ_3, σ_4, shear stress τ, τ_H, saddle Simplified circumferential stress σ5, σ6 (when considering the strengthening plate role
