Structure Analysis 3.1 有限元模型3.1 Finite element model有限元建模过程中作以下简化和假设：（1） 接管直径相对于容器侧板尺寸而言很小，模型忽略接管对容器强度的削弱作用；（2） 对门的连接方式进行简化处理，将角钢与门闩连成一体，并以平面壳单元代替一毫米后的密封板；（3） 假设封板与门之间的摩擦系数为0.3；（4） 不考虑工作温度下产生的热应力作用；（5） 不考虑焊缝的影响。The following simplifications and assumptions are used in

15、 Finite element modeling process:(1) Relative to the size of the container side panels, the diameter of the pipe is small, the model ignores the weakening effect of the strength of the container.(2) The model simplifies the connection of the door,connects the steel anger and bolt as a part and use t

16、he shell element instead of 1mm thick sealing plate.(3) The model assumes the coefficient of friction between the door and the covered plate is 0.3.(4) The model ignores the role of the thermal stress generated in the working temperature.(5) The model does not consider the impact of the weld.对于静强度分析
