摘　　要：针对某片式悬臂型接触件,建立ABAQUS插拔循环仿真模型,并通过试验验证了模型的准确性。采用参数试验法研究弹片圆弧区半径、水平长度和宽度对接触件插拔性能的影响规律,发现接触件弹片圆弧区半径和水平长度对间隙变化值影响较大,弹片宽度与插入力、保持力和间隙变化值趋近于线性关系。联合最优拉丁超立方与响应面法(Opt LHD-RSM,optimal latin hypercube design-response surface methodology)建立接触件多参数耦合模型,优化其结构。优化后,接触件间隙变化值降低82.20%,插入力降低34.38%,插拔性能得到提升。An ABAQUS plug-and-pull cycle simulation model was established for investigating the cantilever contact.The rationality and accuracy of the model was verified through experiments.The influence on the plug-and-pull performance of the contact in terms of the circular radius,the horizontal length,and the width of the shrapnel has been individually assessed.It is found that the circular radius and the horizontal length of the shrapnel have great impacts on the value of the gap changing.The relationships between the width of the shrapnel and the inserting force,as well as the retention force and the gap changing values,are both linear.The Opt LHD-RSM(Optimal Latin Hypercube Design Response Surface Methodology)method was used to establish a multi-parameter coupling model of the contact for structural optimization.As a result,the gap changing value of the contact and the insertion force have been respectively reduced by 82.20%and 34.38%,thus improving the plug-and-pull performance.
