基于ABAQUS的端子钣金件有限元分析与结构优化

Finite Element Analysis and Structural Optimization of Terminal Sheet Metal Parts Based on ABAQUS

摘要: 针对电子产品中金属端子钣金件由于长时间承受外部载荷导致结构发生变形甚至破坏从而影响信号和电流传输的情况，需要对端子钣金件进行有限元静力分析与结构优化。首先，本文利用建模软件Solidworks建立某端子钣金件结构的三维模型。然后，将建立的三维模型导入有限元仿真软件Abaqus中，对端子钣金件在载荷边界条件作用下进行静力学有限元分析。最后，在不改其余参数及体积的前提下，利用Abauqs优化模块针对钣金件进行结构优化，并对优化后的仿真结果进行分析。结果显示，结构优化后的端子钣金件有效缓解了端子根部的应力分布，使其最大等效应力未超过许用屈服应力，符合设计要求。综合分析求解的结果在提高端子钣金件工作性能上有较大参考价值。

Abstract: For the situation that the metal terminal sheet metal parts in electronic products are deformed or even damaged due to the external load for a long time, thus affecting the signal and current trans-mission, it is necessary to carry out finite element static analysis and structural optimization of the terminal sheet metal parts. First of all, this paper uses the modeling software Solidworks to es-tablish a three-dimensional model of a terminal sheet metal part structure. Then, the established three-dimensional model is imported into the finite element simulation software Abaqus, and the static finite element analysis is carried out on the terminal sheet metal parts under the action of load boundary conditions. Finally, without changing the rest of the parameters and volume, Abauqs optimization module is used to optimize the structure of the sheet metal parts, and the optimized simulation results are analyzed. The results show that the structurally optimized terminal sheet metal part effectively relieves the stress distribution at the root of the terminal, so that its maxi-mum equivalent stress does not exceed the permissible yield stress, which meets the design re-quirements. The results of the comprehensive analysis and solution have a greater reference value in improving the working performance of the terminal sheet metal parts.
