利用Ansys有限元分析软件对某一安装架结构进行了动力学仿真分析,首先进行了模态分析,在此基础上进行了随机振动的PSD(Power Spectral Density)分析,通过分析,提出了结构的改进方案。说明了在产品的设计过程中,对结构进行动力学仿真分析,可以预测产品的环境适应性,寻求最优化的设计方案,并缩短产品的开发周期,降低开发成本。

The dynamic simulation of a bracket structure is done via Ansys,a FEA(Finite Element Analysis) software program.First,the modal analysis is done,then the PSD(Power Spectral Density) analysis of random vibration is studied.The improved design is presented.The dynamic simulation plays an important role in product design cycle.It is helpful not only in seeking optimum solution for product,but also efficient in shortening the research cycle,reducing cost.
