【摘要】 <正>The road surface is always irregular for lots of reasons,such as construction,weathering,and differential settlements,which is called roughness in civil engineering.The road roughness has been studied much,for its significant effects to the vehicle responses,the comfort of passenger and the civil structures(such as road,bridge). The profile simulation has been developed well by Dods,which is taken as International Organization for Standardization(ISO)specifications in 1972,as a periodically modulated random process.更多还原
