基于ANSYS的航空电子设备安装架模态分析

摘要

性能优良的安装架可以减少机载设备在工作中承受的机械振动,是机载设备正常工作的保障.基于安装架的结构形式和工作状况,利用ANSYS软件建立了安装架的参数化有限元模型,并通过数值分析获得了该安装架的模态频率和振型.实验结果表明该分析方法的正确性,为其全面动力学特性分析和结构优化设计提供了参考.%In order to reduce the mechanical vibration of airborne equipment. Excellent performance of the mounting frame can en-sure normal work security of the equipment. Based on the structure of its form and working conditions, the bracket parametric finite ele-ment model of ihe accurate numerical analysis is established by using ANSYS to obtain the modal frequency for its overall dynamic characteristics and structure optimization design . The experiments show that this method is correct, and can offer the overall kinetics characteristic analysis and structural optimization for design reference.
