| 摘 要： | 基于无限脉冲响应数字滤波器理论,根据ISO2631-1：1997（E）标准中频率加权系数设计了一个频率加权滤波器。通过频率加权滤波器对加速度时间信号进行滤波,获得加权加速度的时域数据和振动的峰值系数。通过分析,在随机振动下,各轴向的振动峰值系数一般不超过9,可用基本评价方法评价汽车平顺性;在冲击振动下,座椅、座椅导轨和...

| Abstract: | Based on the infinite impulse response digital filter theory,a frequency weighting filter was designed according to the frequency weighting factors in the standard ISO2631-1:1997(E).The weighted acceleration data in the time-domain and the crest factor of vibration were obtained by the filtering of the time-domain acceleration signal using the fuequency weighted digital filter.The analyses showed that the crest factor of the vibration in all axes is lower than 9 under random vibration,the basic evaluation m... |
