摘要/Abstract

摘要： 针对航空航天设备中的重要零件——圆柱式开双槽电连接器建立了接触计算模型，推导了接触件间的摩擦力与插针插入量之间的数学关系.运用SOLIDWORKS 软件实现了38999系列22^#通用接触件参数化建模，利用ABAQUS有限元分析软件进行了接触性能仿真分析，得到了以插拔力为考核指标的插孔端部的最佳收口量为0.66mm.又对插孔结构进行了参数灵敏度分析，利用模糊综合评价法确定了插孔结构的最优参数，即插孔簧片长度为3mm、开槽宽度为0.43mm和插孔端部收口量为0.67mm，此时接触件的接触性能最佳.

关键词: 电连接器, 接触性能, 仿真, 插拔力, 灵敏度

Abstract: The contact calculation model for the cylindrical double groove electric connector， a significant component in aerospace equipment， was established. The mathematical relationship between the contact friction force and the insertion amount of pins was derived. The parameterized modeling for 38999 series 22^# general contact elements was performed using SOLIDWORKS， and the contact performance was analyzed using ABAQUS finite element analysis software. It is obtained that the optimum closing amount of the socket end， with the insertion force as an assessment index， is 0.66mm. Sensitivity of the socket structure parameters was analyzed， and its structural optimization was determined based on the fuzzy comprehensive evaluation method. The optimum contact performance is obtained when the length of the socket reed is 3mm， the width of the socket slot is 0.43mm and the closing amount of the socket end is 0.67mm.

Key words: electrical connector, contact performance, simulation, insertion force, sensitivity
