基于ANSYS/LS-DYNA的产品跌落仿真

Drop-Impact Simulation of Product Based on ANSYS/LS-DYNA

对各种工业产品进行跌落测试数值仿真是ANSYS/LS-DYNA程序的一个重要的应用领域。作者以个人数字助理的有限元跌落仿真分析为例,讨论了ANSYS/LS-DYNA跌落测试模块(DTM)提供的数值仿真分析方法及实现过程。

The drop-impact data simulation of various industrial products is a very important application field in ANSYS/LS-DYNA program.Taking the analysis of the PDA＇s finite element drop-impact simulation as the example,this paper discusses about the numerical simulation method and the implementation process in the ANSYS/LS-DYNA Drop Test Module（DTM）.
