摘　　要：以某型越野汽车为研究对象,在某试验场不同道路条件下进行了整车载荷信号采集,并介绍了信号采集方法。为提高数据采集的真实性和可靠性,对试验场载荷信号进行了信号时标的一致性处理、异常点判别与剔除、趋势项消除、数据检验、样本选择及傅里叶低通滤波等预处理,为下一步进行室内道路模拟试验载荷谱的强化处理奠定了基础。This paper takes an off-road vehicle as research object, and introduces vehicle load signal acquisition under different road conditions in a proving ground, the signal acquisition method is also introduced in the paper. To improve authenticity and reliability of data acquisition, consistency treatment on signal time-tag, abnormal point identification and removal, tendencY elimination, data inspection, sample selection as well as Fourier low-pass filter pretreatment, etc. are made to the load signals from the proving ground, this lays foundation for the enhancement of load spectrum of the indoor road simulation test.
