摘要
针对目前ANSYS大型商用数值分析软件的shell单元无法得到应力线性化数据,从而使得化工设备和压力容器的安全评估无法实施的问题进行了shell单元建立的典型化工设备模型的应力线性化研究,通过具体分析shell51单元的数据,给出了应力线性化评价数据的计算方法和相应计算公式,实现了shell51单元模型的应力线性化分析计算。同时,本文通过实例分析,得到了一些重要的结论,对于指导利用shell51单元模型进行分析设计评估和化工设备的安全评价具有重要的作用。
ANSYS, a widely used numerical analysis soft - ware, has difficulty in getting stress linearization date from its shell element type at present, then the safety evaluation in chemical equipment and pressure vessel can t be carried out. According to the problem, this paper studies stress linearization of typical chemical equipment based in the shell element type. Through the detailed analysis in the data from shell51, the? calculation method and corresponding formula have been obtained, and then the analysis...
