Review of Road Roughness and Vehicle Vibration Model

In order to simulate the vehicle dynamic load caused by mad roughness and analyze the dynamic response of pavement in the vehicle-mad or vehicle-bridge interaction system more precisely, the definitions of mad roughness were reviewed. The evolution indices, the evolution methods of mad roughness and the relationship among the evolution indices were introduced. The testing methods and instruments of mad roughness were classified and elaborated.Then the numerical simulation methods of mad roughness were analyzed, and the better numerical models which more approximate to practical situation were recommended. Afterwards, the vehicle vibration models used to analyze the dynamic load caused by mad roughness were introduced. At last, the evolution indices of mad roughness, the numerical simulation methods of mad roughness and the developing trend of vehicle vibration models were summarized. The suggestion on the various calculation parameters of coupling vibration which used to analyze the interaction between vehicles and mad surface was put forward. It is found that IRI should be the unified evolution index of road roughness. The ARMA model and AR model were recommended to simulate the random excitation. The study results can provide the theoretical basis for analysis of dynamic response of pavement under random dynamic load.
