摘　　要：针对汽车悬架的振动特点,对F-5103数据采集系统进行标定,并通过实车检测,验证标定结果准确、可靠.基于F-5103数据采集系统,对具有钢板弹簧非独立悬架的BJ2020S商用车和具有麦弗逊独立悬架的AUDI100乘用车进行了检测.经幅、频两域分析并提取特征信息,获得了被测汽车前悬架隔振性能参数,如固有频率f_0、阻尼比ξ、悬架效率η和左、右悬架效率差Δη,绘制了被测汽车前悬架振动信号的自功率谱密度图形,求得了其一阶固有频率处的带中功率ΔN,得出了被测汽车的前悬架特性并评价了其隔振性能.In allusion to the characteristics of anti-vibration performance of vehicle suspension, F -5103 acquisition system is demarcated in this paper, and the accuracy and reliability of demarcating result are validated by testing BJ2020S commercial vehicle with leaf spring rigid axle suspension and AUD1100 passenger car with MacPhersan independent suspension are tested based on F - 5103 acquisition system. The characteristic information is distilled according to the analysis in terms of time and frequency. The anti-vibration performance parameters of front vehicle suspension are obtained, such as nature frequency, damp rate, suspension efficiency and right-and-left suspension efficiency dispersion. The PSD figures of vibration single of front vehicle suspension are protracted, and the power in the band containing one order nature frequency is gained. The characteristics of front vehicle suspension are received and anti-vibration performance is evaluated.
