摘　　要：目前采用约束单元SPR2建立无铆钉铆接的简化有限元模型,建模简单,仿真精度较高,但Hyper Mesh 12.0版本不支持SPR2建模,导致了整车建模效率较低,因此本文应用Tcl/Tk语言和Hyper Works内置函数开发了整车铆接SPR2的有限元快速建模模块。并以某轿车铆接建模为例,验证了该模块的可操作性。该模块可根据用户选择的铆接点自动识别连接板件,极大地提高了建模效率,同时可有效地避免软件的升级更新,节约费用,并为其他新型连接的有限元快速建模提供了一种参考方法。At present,the constraint element SPR2 is applied to establish a simplified finite element model of clinching joints for its simple way for modeling and accurate simulation.However,HyperMesh 12.0 version can not support SPR2 modeling,which leads to the low efficiency of vehicle modeling.Therefore the Tcl/Tk and the built-in function of HyperWorks are used to develop finite element fast modeling for the vehicle clinching joint of SPR2.A certain car riveting modeling is taken as an example to verify the availability of the module.The module can automatically identify the connected plates according to the nodes selected,which greatly improves the modeling efficiency,avoids the software updates and saves the cost,and it provides a reference method for other new joints fast modeling.
