摘　　要：利用DHM以及平稳与非平稳FD过程路面不平度之间的关系,模拟了平稳和非平稳FD过程的路面不平度。通过对实测路面不平度进行平稳或非平稳FD过程最大可能性估计的识别,研究了对实测路面不平度的不同数据量的模拟,结果表明:所模拟的路面不平度与实测路面不平度基本相近。Using Davies-Harte Method （DHM） and the relationship between the stationary and nonstationary Fractionally Ditterenced （FD） processes of road roughness, two kinds of road roughness, stationary and nonstationary FD processes were simulated. Through the maximal likelihood Estimators of stationary/nonstationary FD process to the actually measured road roughness, simulations of road roughness of various data to the actually measured road roughness were studied, which shows that these simulations are closer to the actually measured road roughness.
