锅炉的应力及位移有限元数值分析

Finite Element Numerical Analysis of the Boiler's Stress and Displacement

摘要: 利用美国MSC提供的CAE软件对锅炉的应力分布及位移变形进行了分析.利用其便捷的前后处理软件MSC/PATRAN建立了几何模型和有限元分析模型,并利用MSC/NASTRAN对模型进行了计算和分析.同时,利用材料力学的经典强度理论进行了计算和强度校核.结果表明两种方法得到的计算结果基本吻合.

Abstract: The stress distribution and displacement of the boiler are investigated by CAE software. The geometrical model and the finite element analysis model are established by MSC/PATRAN, and these models are calculated and analyzed by MSC/NASTRAN. At the same time, the classical strength theory of material mechanics is applied to their calculation and strength check. It is shown that the numerical and theoretical methods have the same results.
