In order to obtain real physical motion of vehicle and interaction in the virtual scene, the virtual simulation plat?form integration scheme based on open dynamics engine was proposed. Building simple vehicle dynamics model with four degrees of freedom, analyzing its ODE characteristics and rigid connection mechanism, analyzing the suspension system between the body and the wheel, using ODE Hinge-2 to simulate, the dynamic equation of rigid body was analyzed. Rigid body collision detection algorithm was researched based on Quest3D and VS2005, a virtual simulation platform for finish?ing vehicle motion and collision detection was built, it could output real-time vehicle dynamic parameters. The test shows that the virtual simulation system has a high degree of immersion, interaction and practicality.
