Finite element analysis and optimization design of the pressure vessel

针对传统设计中压力容器的材料浪费问题,提出基于有限元分析的压力容器的优化设计方法.该方法首先利用有限元法对压力容器进行分析并提取分析结果中的相关参数,然后利用优化设计方法进行定量计算,最终得到既满足性能指标又满足设计指标的设计参数.实际结果表明,基于有限元分析的优化设计方法,在工程实际应用中可有效发挥作用.

According to pressure vessel material waste problem in the traditional design, this paper puts forward the pressure vessel optimization design method based on finite element a- nalysis. In this method, firstly the finite element analysis is applied to carry out stress calcu- lation, and the related results parameters are extracted to be use following calculation. Then the quantitative calculation is conducted by using optimization design method, and the best design parameters which meet performance indexes are got. At last, this method was used for the optimization design of pressure vessels. Practical results proved the validity and the practicability of this method in the pressure vessels design.
