车辆虚拟试验系统的实现

Realization of a Virtual Experiment System of Vehicles

论述了基于虚拟现实技术的汽车虚拟试验系统 ,利用 ADAMS动力学软件获取的动力学分析数据来驱动虚拟场景中的试验车辆 ,同时配合虚拟仪表准确动态显示车辆的运动状态参数 ,实现车辆的虚拟试验过程仿真。用户可操纵鼠标。

In order to improve the technique of vehicle experiment on road, a vehicle virtual experiment system was put forward. The dynamics software--ADAMS was adopted to obtain experimental data, which were used to control the motion of vehicle in virtual experiment scene. Then the vehicle virtual experiment system was developed making use of Visual C++6 0, WorldToolKit and Component Works, which included scene graph building, the vehicle experiment simulating, and the interaction realizing between users and scene. Using this system, the test vehicle moves on the screen like an actual vehicle moves in test field. With the help of virtual meter, the exact values of motion vehicle parameters can be obtained and the interaction with virtual scene can be realized using keyboard and mouse. By means of AGCViewerG stereo hardware, users can immerse in the virtual experiment scene.
