【摘要】 路面不平度在越野汽车平顺性和操纵稳定性中起着重要的作用.利用试验法和软件重构法对路面不平度进行了论述;试验法能够建立中国典型道路谱原始数据库,对以后进行道路方面的工作具有重要的指导意义;重构法是用matlab软件运用谐波叠加法对路面不平度进行重构.重构的数据既可作为相应道路谱的期望数据,也可为室内道路模拟试验台提供预期的驱动信号.更多还原

【Abstract】 The road surface roughness plays a vital role in ride and handling for a cross-country vehicle.The testing procedure of road surface roughness is discussed and the method of software reconstruction for the roughness is introduced.The purpose of the testing method is to establishing a database for Chinese typical road surface spectrum,and the reconstruction is based on the superposition of harmonic waves.The reconstructed data can be served as expectations for corresponding road spectrum or as expected driving signals on an indoor road simulator.更多还原
