摘　　要：建立了汽车四轮随机输入的滤波白噪声模型。该模型考虑了汽车左右轮和前后轮的相关,通过相干函数得到了时域模型的系数。最后对上述模型入进行了计算机模拟,得到了可以进行汽车时域分析的随机波形。Wave-filted white noise model was established on random inputs of automobile with four wheels.This model takes the correlation between four wheels into consideration.The parameters of the models were obtained by using coherence function. Finally, the computational simulation of the road model was carried out and the random wave forms to be applied to the response analysis of automobile was obtained.

关 键 词：汽车 时域相关 随机输入 滤波
