摘　　要：针对继电器引脚与插拔结构之间接触正压力(以下简称正压力)的优化设计问题,对设计模型仿真分析参数进行了校准,分析了正压力测量方法的误差,并阐述了设定合理正压力值的原理和过程,进而提出了一种正压力的优化设计方法。该方法的基础数据来源于有限元仿真分析,采用基于响应面代理模型的遗传算法完成了最优值的求解。首先根据设计变量的取值范围建立了一定数量的3D模型,再利用Abaqus软件进行了有限元仿真分析,获得了设计变量与正压力一一对应的数据群组。基于数据群组,在Matlab软件中建立了响应面代理模型和使用遗传算法进行设计变量最优值的求解。最后,测量和分析了优化后样品的正压力值。研究结果表明:优化后正压力的测量值与分析值误差为8.60%,两者基本吻合,证明该方法是解决该类插拔结构正压力优化设计的有效方式。Aiming at the problem of the contact normal force optimization design between the pin of relay and the pluggable structure,the analyze parameter of design model was calibrated,the deviation of test method for contact force was analyzed,and the principle and process of setting reasonable contact force value were discussed,further step an optimization design method for the contact force was presented. The basic data of this method is from FEA simulation,and the GA（ Genetic Algorithm） which based the RSM（ Response Surface Methodology）was used for calculating the optimal value. Firstly,enough 3D models according to the value range of design variables were created,and the contact force of every model was simulated by FEA in Abaqus to get the data array which include the design variables and contact force. Secondly,based the data array,the RSM agent model was created and the optimal value of design variables was calculated by GA in Matlab.Lastly,the contact force value of optimized sample was tested and simulated. The results indicate that there is 8. 60% deviation between the test and simulated value,and which are reasonable for engineer application. So this method is effective way for optimizing and testing the contact force of the pluggable structure.
