【摘要】 路面谱研究是履带车辆行驶平顺性试验中的关键条件,路面谱模型的好坏直接影响到仿真的准确性,通过对国家标准GB7031-86中路面谱模型的研究,利用AR模型法模拟了国家标准路面谱的典型路面模型,并对该路面谱模型利用周期图法进行了谱分析,对其功率谱密度进行了验证,根据模拟生成的随机路面谱在Adams中生成路面。更多还原

【Abstract】 One of important researches in Tracked Vehicle Compliance Simulation experiment is Road Roughness Research. The accuracy of simulation directly depends on the model of road roughness. AR model was used to simulate typical road model of National Standards through the research of Road Roughness National Standards GB7031-86. Spectrum analysis was proceeded for the road roughness model by using periodogram method. Its power spectral density was validated. At last, road surface in Adams was created according to the random road roughness generated by simulation.更多还原
