装甲车行驶中车体姿态的仿真是模拟驾驶训练系统的关键技术.为实现不同地形下基于虚拟现实的装甲车辆驾驶模拟,本文提出了基于虚拟现实的装甲车辆运动仿真方法.首先,构建装甲车辆的结构、外形和真实的地形,采用第一和第三视角同步显示驾驶场景;其次,建立车辆行驶的动力学模型,求解车身在不同地形下的车身姿态数据;最后,通过Unity3D引擎实现整个场景和车体姿态的动态渲染.通过实验证明,该方法能够准确的模拟各种地形条件下的车体姿态,真实的仿真车辆的运行状态.

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.
