基于关闭能量的汽车滑移门闭合性能优化
|
摘要
为解决某车型滑移门关闭力过大等问题,通过滑移门关闭实验及基于ADAMS/View多体动力学仿真软件分析了滑移门各部件对最小关闭能量的影响,找到了影响滑移门关闭能量的主要因素,并针对主要影响因素提出了优化方案降低关闭能量消耗。通过减小密封胶条压缩位移、优化密封胶条断面形状降低CLD曲线中4～6 mm位移范围内的曲线斜率、减小中铰链销扭簧最大扭矩及预载、适当减小限位器配合间隙等措施,对滑移门闭合性能进行了优化,优化后整个系统的最小关闭能量降低了25%,优化效果明显。
The effects of sliding door's components on the minimum closing energy of sliding door were analyzed by sliding door closing experiment and ADAMS/View multi-body dynamics simulation to solve the excessive sliding door closing force on a certain kind of vehicle. The main influencing factors of the door closing energy were discovered and the optimization schemes of reducing the closing energy consumption were proposed based on these factors. And the sliding door closing property was optimized by some measures,such as decreasing the compression displacement of weather-strip,changing the section shape of the weatherstrip to lower the slope of its CLD between 4 to 6 millimeter displacement range,decreasing the maximal torque and the preload of torsional spring,and decreasing the fit clearance of stopper suitably. The minimum closing energy of the sliding door system was reduced by 25 % after optimization,and the effect was obvious.
