开式压力机床身有限元分析与结构优选

FINITE ELEMENT ANALYSIS AND STRUCTURE OPTIMIZATION FOR OPEN-PRESS FUSELAGE

摘要: 分析了开式压力机床身的结构特点，然后介绍了应用有限元法对开式压力机床身进行结构分析时的力学模型简化方法，并结合若干工程实例，对开式压力机床具进行了有限元分析与结构优选，取得了既减轻床具重量、又提高强度和刚度的显著效果，为结构的合理设计与改进提供了可靠的理论依据。

Abstract: In this paper, the structural characteristic of open-press fuselage was first analyzed. Thenits mechanics model simplification method for thestructural analysis by finite element method was rec-ommended. Its finite eIement analysis and structureoptimization were made for open-press fuselage withseveral practical examples. A remarkable effect onreducing its weight and increasing its strength andrigidity was achieved. It provided a theoretical basefor reliable design and improvement of the structure.
