| 摘 要： | 讨论了一种关于路面不平度模拟信号生成的新方法。根据路面不平度的统计特性，构造出一个下三角滤波器，再由实测信号的统计特征来确定滤波器的值，并利用正态白噪声通过该滤波器来得到所需的信号。实验表明该信号较真实地反映了路面的统计特征，在实际应用中能取得较好的模拟效果。

| Abstract: | A new approach to create a signal of road simulation was studied.We constructed a bottom triangle filter by the statistic attribute of road profile, and determined the worth of the filter by the statistical attribute of practical signal.Then we had the normal distributional white noise pass filter to get the expectative signal. It has been sure in the practice that this signal can represent the statistic attribute of road profile and get a better simulated result. |
