摘要
利用有限元分析软件Abaqus,对某种车用连接器端子结构进行分析,得出端子插拔力及应力和塑性变形等,并得到端子的插拔力分别为8.4276 N和4.0185 N,与试验结果相符;其最大应力值为520 MPa,超过了材料的屈服强度,即在第1次插拔时产生了塑性变形,因此第1次拔出后喇叭口没有恢复到原来的状态,而是产生了0.134 mm的间隙。研究结果表明,有限元模拟仿真结果与试验结果相符,应用有限元软件对车用连接器进行分析能够为类似产品的设计研究提供依据,可以有效节省产品开发成本。
This paper analyzes a certain vehicle connector terminal structure based on the finite element analysis software Abaqus, and obtains data of terminal mating and unmating force, stress and plastic deformation. The terminal mating and unmating force are 8.427 6 N and 4.018 5 N which consistent with the test results; the maximum stress value is 520 MPa which exceed the yield strength of the material. That is, plastic deformation occurs during the first plug. So the bell pull is not restored to its original state, and left a 0.134 mm gap after the first unmating.The results show that the finite element simulation results are consistent with the experimental results and the application of finite element software to analyze vehicle connector can provide a reference to similar products, which can save the product development cost effectively.
