摘要
针对某汽车滑移门系统平顺性能,运用正交试验设计方法进行了优化研究。在滑移门的开、闭过程中,以中导轨及其走轮臂转动销轴的X向、Y向位移作为优化变量,以滑移门质心运动轨迹优劣程度作为设计指标。在保证滑移门在运动过程中不与车身发生干涉的情况下,初步给定了4个优化变量在各自方向上的取值范围。运用正交试验提取多组试验方案,分别求解出滑移门质心运动轨迹,对比分析轨迹曲率特性。研究结果表明,中导轨及其走轮臂转动销的位置对于汽车滑移门运动平顺性能有着重要的影响。
Aiming at automotive sliding door ride performance,the optimization was finished by using the orthogonal experimental design.While opening or closing sliding door,the middle sliding rail and arm-shaft＇s displacements in axis X and Y were taken as optimization viriables,and the sliding door centriod trace＇s merits were taken as design specification.Initially,the ranges of four optimization variables in their own directions were given while there was no occurrence of interference between sliding door and body in process of opening sliding door.Some orthogonal texts were done and sliding door centroid trajectory curves were caught.These traces＇ curvature characteristics were compared.The results indicate that middle sliding rail and arm-shaft＇s displacements have a significant impact on ride performance of automotive sliding door.
