摘要
整车驾驶性开发中,整车抖动是个至关重要的问题,其严重影响驾乘人员的舒适性。本文针对某DCT车型抱怨的M1挡抖动问题,首先通过整车测试采集相关数据,其次借助MATLAB软件,应用时频分析的阶次跟踪技术进行问题分析,并通过MATLAB滤波设计工具进行优化,最后抖动问题显著改善。
Vibration is a important issue in the drivability performance development of vehicle,which seriously affected driver and passenger’s comfort.In this paper,vehicle test was used to collect vibration related data,MATLAB software,time-frequency analysis and order tracking are applied for M1 vibration issue analysis.And based on MATLAB FilterDesigner tool,vibration issue was improved a lot with filter processing.
