基于IQS的汽车制动抖动问题改进方法研究
|
摘要
汽车出现制动抖动现象后,车辆生产企业面临着索赔和及时消除故障的难题。从实际角度出发,根据客户对于具体车型制动抖动IQS得分进行分析,综合考虑导致抖动的主导因素和改进成本,从制动盘形成激励源着手,通过设置改进目标,模拟DTV增长实验、制动盘硬度与离散度检测及使用后的制动盘DTV超差问题来分析原因并提出控制库存车,加强售后对于制动盘的保养,控制制动盘热处理时间等改进措施,通过客户故障率反馈信息统计数据来验证改进效果,为复杂的制动抖动形成问题找到直接有效的解决途径,同时也对激励源响应导致的制动抖动因素提出改进方向。
After braking jitter occurs in automobiles,vehicle manufacturers are faced with the problem of claim and timely elimination of faults.From the practical point of view,according to the customer's IQS score of brake jitter for a specific vehicle,the paper comprehensively considers the leading factors leading to the jitter and the cost of improvement.Starting from the formation of an incentive source for the brake disc,the paper analyses the reasons and puts forward the control inventory by setting improvement targets,simulating DTV growth experiment,testing the hardness and dispersion of the brake disc and DTV overshoot after use to strengthen after-sales maintenance of brake discs,control brake disc heat treatment time and other improvement measures.Through customer failure rate feedback information statistics for verifying the improvement effect,this paper finds a direct and effective solution to complex brake jitter problems,and also to a proposed improvement direction responded by brake jitter factors.
