摘　　要：螺栓联接广泛地应用于动车组结构中,其仿真分析已经成为提高螺栓可靠性的重要手段。针对螺栓有限元接触分析前处理过程中存在的直接划分螺栓孔不能得到较好质量网格等问题,运用Tcl脚本语言结合HyperMesh自身快速编辑面板,开发了一套螺栓接触前处理分析工具。同时,为规范操作流程,利用Process Studio开发出仿真分析流程模板,将螺栓接触分析前处理工具嵌入流程对应节点上,通过流程的自动加载和集成的工具实现螺栓孔网格的快速划分,提高网格质量和后处理求解成功率,有一定的实际应用价值。Boh are widely used on EMU. Simulation analysis has become one of the most imporiant means to imprtove the reliability of bolt. For pre-processing of boh conlact,there are problems about direcl meshing the bolt hole which cannol get high qualily grid. Therefore, Tel language and the quick edit pannel of HyperMesh are used Io develop Ihe Ioo1 of pre-processing of boh conlacl. At the same time, Process Studio is used to develop simulalion process templates, and embed Ihe tool of Dre-processitg of boh contact on corresponding node. The automatic：ally loaded process and the integrated tools will achieve quickly meshed the boh holes,improving the quality of grid and the solving succeess rate of after-process,which is of practical value.
