摘要
路面输入模型在汽车平顺性和操纵稳定性分析研究中是很重要的,对谐波叠加模型的建立进行了理论分析和探讨;编制了运用该模型生成随机路面谱的软件,对国标GB7031—87中规定的各级路面不平度进行了数字模拟,结果表明,该模型能够描述复杂且不规则的路面形状,适应于任意形状的谱密度的平稳随机过程,具有较好的适应性。
The input model of road roughness is one key element in the study of comfortable performance of vehicle. A model of road roughness, named Partial Wave Adding model, is theoretically analyzed and studied in detail. Based on the mathematical model, digital simulation of road roughness is studied. The simulation results show that the model is an easily actualized model and has universal adaptability.
