摘要

针对开槽插孔接触件存在的分离力较离散的现状,提出了基于仿真和田口法优化开槽插孔尺寸以降低分离力的范围和离散度。分析了影响开槽插孔分离力的结构参数,仿真了开槽插孔在不同开槽深度h、开槽宽度d和过盈量δ组合下的分离力大小,并采用田口法对仿真数值进行分析处理,分析结果表明当分离力范围要求为0.3N~0.8N范围时,插孔尺寸参数组合为h=3.7mm,d=0.3mm,δ=0.05mm时,该参数组合具有最强抗干扰能力。对尺寸优化前后的接触件进行分离力对比试验,试验结果表明:插孔分离力均值从优化前0.524N到优化后0.539N,标准差从优化前的0.094变成优化后0.078。基于有限元仿真和田口法的开槽插孔分离力优化为接触件的优化设计提供了参考。

Abstract

In order to solve the present situation of big dispersion degree of the slotted jack contact separation force,Finite element simulation and Taguchi method is proposed to optimize the range and the dispersion degree of the separation force. The structural parameters that affect the separation force of the slotted jack were analyzed,the separation force of the slotted slot in different groove depth（ h）,slot width（ d） and interference amount（ δ） was calculated by the finite element simulation model,The simulation data were analyzed by Taguchi method,The results show that the combination of the parameters is h = 3. 7 mm,d= 0. 3 mm,δ = 0. 05 mm has the strongest anti-interference ability when the separation force range is 0. 3 N ,0. 8 N. The separation force test was carried out before and after the size optimization,The results show that the separation force of the jack is from 0. 524 N to 0. 539 N,and the standard deviation becomes from 0. 094 to 0. 078. The optimization of the separation force of the slotted jack based on finite element simulation and Taguchi method provides a reference for the optimal design of the contact.
