| The vehicle dynamic load caused by roughness pavement is the main reason of fatigue and premature failure of the pavement In order to comprehend the characteristics of force applied under dynamic loads and offer the reference for the pavement design, the vehicle dynamic response to the road caused by roughness is analyzed in the paper. The vertical force applied to the road surface by vehicle can be separated into two components: the static load and dynamic load. It is very important for the vehicle dynamic response to analyze the disciplinarian of the dynamic load deeply. During the study, some vehicle dynamic models are formed, and the some study is carried out based on them. It is analyzed for the influence of parameters to vehicle dynamic response. Only on the basis of reasonable knowing of those can we provide some valuable advice for the further research of road dynamic response. |
