Abstract:The simulation of vehicle body posture in the running of armored vehicles is the key technology to simulate the driving training system. In order to realize the simulation of armored vehicle driving under different terrain based on virtual reality, the method of motion simulation of armored vehicle based on virtual reality is presented in this paper. Firstly, the structure, shape, and real terrain of the armored vehicle are constructed, and the driving scenarios are displayed simultaneously from the first and third perspectives. Secondly, the dynamic model of vehicle driving is established to solve the attitude data of vehicle body under different topography. Finally, the whole scene and vehicle posture are dynamically rendered through Unity3D engine. The experimental results show that this method can accurately simulate the vehicle body posture under various topographic conditions and truly simulate the running state of the vehicle.
