The factor that has affected the handling stability, comfort, power and braking of vehicle's movement almost arise from contact between tyre and ground. Therefore, researching dynamics vehicle-ground system, building a closer to real working condition of tire-ground system model. It is important scientific significance to study of traffic theory, the interaction between tire and ground and improve the vehicle performance.The study of 2-D granule vehicle-ground dynamic model, its calculating result good consistency with experiments.Constructing the 3-D granule vehicle-ground dynamic model to study the interaction mechanism with tire and ground. The main work and achievements as follows:1) 3-D granule vehicle-ground dynamic model was established;2) It has realized the 3-D tyre-ground system dynamics model object-oriented visualization procedure development with Borland C++Builder software;3) It has carried on the contrastive analysis about the computed result and some existing tentative data and finally it appeared that has a very good consistency.The result of this paper some reference value for the study of trafficability characteristic and driving performance of existing vehicles,and through,Providing a new thinking to reach on the dynamics of vehicle-terramechanics. |
