摘　　要：研究了利用三维图形软件3ds MAX对有限元软件ABAQUS仿真模型动画效果进行优化的方法.以1个3层钢框架结构为对象,使用ABAQUS对其进行地震作用下的动力弹塑性时程分析,并得到与各个时间步对应的多个TRML格式模型文件.借助自主开发的3个3ds MAX功能插件实现TRML格式模型文件向3ds MAX的批量导入及动画模型的快速生成.利用3ds MAX制作完成了具有一定真实感工程场景动画.研究结果表明:所开发的功能插件在提高工作效率方面具有显著效果,且与ABAQUS自动生成的动画相比,利用优化方法所得动画效果的真实感更强.This paper presents the optimization method of 3Dgraphics software 3ds MAX on the animation generated from the simulation model of finite element software ABAQUS.A three story steel frame structure is taken as the experimental subject.Using ABAQUS to carry out the dynamic elastic-plastic time history analysis under seismic action and obtain files of multiple TRML format corresponding to each time step.Afterwards,with self-developed 3ds MAX plug-in,it realized batch import of TRML format files to 3ds MAX and the animation model is quickly generated.Finally,using 3ds MAX to complete the experimental scene animation which looks more real.The research results show that the plug-in in this paper has significant effect on improving work efficiency.Moreover,compared with the automatically generated animation of ABAQUS,the animation obtained through the method has stronger sense of reality.
