| 摘 要： | 高压釜是压力精炼的核心部件,该文以一典型的压力精炼用大型高压釜优化设计为例给出一种基于有限元模拟结果和准则法的大型高压釜优化设计方法。首先给出一压力精炼用大型高压釜设计参数和技术指标,以重量最小化为目标,建立高压釜优化设计的数学模型;其次应用前处理软件Hypermesh和有限元软件Abaqus建立高压釜的三维有限元模型;然后基于满应力法和高压釜结构及承受载荷特点,构造优化算法,并应用构造的优化算法对高压釜进行优化设计;最后对设计的高压釜进行安全评定、模态分析和稳定性分析。安全评定结果表明高压釜各部件满足安全需要,模态分析结果表明高压釜动力特性能够满足设计要求,稳定性分析表明在承受意外附加载荷情况下设计的高压釜不会发生整体失稳。

| Abstract: | The high pressure vessel is the key component of pressure refining. Based on the optimality criteria method and finite element results, an optimization design method is illustrated through a classical pressure vessel design. Firstly, the technical specification and design parameters are given, and the mathematical model of the optimization design is constructed by taking the weight minimization as the optimization design objective; secondly, the 3-D finite element model of the vessel is built by the preproc... |
