摘要
加速度信号的精度决定了汽车瞬态响应分析的结果。在分析了道路振动信号固有特性的基础上,提出了基于频域积分的振动信号处理方法。该方法简单实用,具有很好的通用性,对汽车的瞬态响应分析提供了足够精度的数据。
The precision of the aceerleration signal and its pretreatment determines the effects of the transient response analysis.Based on the analysis of the inherent characteristic of the signal,a method that called the process of the vibration signal process based on frequency domain integration is introduced.It＇s simple and effective method,and has good precison for the transient response analysis.
