摘　　要：针对越野车外覆盖件抗凹分析流程中考察点多、加载工况复杂、工作效率低的现状,采用TCL/TK语言和基于HyperMesh前处理平台,开发一套简单、高效、便捷的可视化CAE抗凹分析自动化流程。该流程主界面简单,可以按照需求自动完成网格细化、压头创建和工况分析,操作简便。以某越野车发动机盖抗凹分析为例,验证该抗凹分析自动化流程的高效率和分析结果的准确性。As to the issue that the inspection points number is large,the loading conditions are complex and the work efficiency is low in the dent resistance analysis process of the off-road vehicle outer panel,a set of visualization CAE dent resistance analysis automation process is developed by using TCL/TK language and HyperMesh pre-processing platform,which is simple,efficient and convenient.The main interface and the operation of the process are simple,and it can automatically complete the mesh refinement,the indenter creation and the working conditions analysis according to the requirements.Taking the dent resistance analysis of an off-road vehicle hood as an example,the efficiency of the automatic process and the accuracy of the analysis results are verified.
