摘要

基于NX Nastran软件以及舱体保持架的结构特点,采用梁、板、实体、质量点等多种单元创建该构件的有限元模型。使用该模型计算出通信舱保持架的变形量及最大应力,并结合实验从变形的角度验证了模型计算精度。基于仿真结果寻找出刚度较小的框架部位及应力集中点,进行结构优化并分析验证,结果表明,改进后的框架结构刚度、强度显著提高。这种多单元混合建模的方式可广泛应用于大型结构件的设计、优化等工作中,对结构方案的制定及改进提供指导依据。

Abstract

Based on the software NX Nastran,the Cabin Cage finite element model was established,using beam,plate,solid and mass element properties. The structure’s max deformation and max stress were counted out,and an experiment was did to confirm the accuracy of the finite element model. Based on the simulation results,the authors optimized some part of the structure and did another simulation. The further results showed that the stiffness and strength of the optimized structure had been improved significantly. This modeling method with serious kinds of element properties can be widely applied in design and optimize of large-scale structures.
