| 摘 要： | 汽车已成为大众生活的必需品.要提高车辆的平顺性,关键就要使其振动的频谱不在人体的敏感区域.以Matlab软件为计算平台,对从实车上采集的数字信号进行处理,得到其振动频谱.通过频谱分析,可以确定其参数是否合适.这对如何处理振动信号及提高汽车的平顺性有现实的意义.

| Abstract: | The car is a necessary tool for people's lives.If higher level of car ride comfort is wanted, the key is that spectrum of vibration signal must be changed,which means that it is not sensitive for man.Based on calculating platform of Matlab software,this paper has disposed of digital signal that had been assembled from vehicle vibration.Through analyzing spectrum,the author can know whether the parameters of the car are appropriate or not.The paper is of practical sense for man to deal with vibration signal ... |
