基于VR的车辆振动虚拟测试平台研究

Study on the Virtual Testing Platform of Vehicle Vibration Based on VR

针对传统车辆振动研究方法的缺点,并根据基于VR的虚拟测试技术的概念和理论模型,提出了由虚拟现实子系统、模型子系统和虚拟仪器子系统构成的基于VR的车辆振动虚拟测试平台的体系框架,研究了基于VR的车辆振动虚拟测试平台的实现方法,并给出了车辆振动的虚拟测试结果显示。结果表明:通过该平台,用户可以分别在三种不同的观察模式下同时观察车辆的振动及其时域和频域信号。

Aimed at the disadvantages of the traditional research methods of the vehicle vibration, in terms of the concept and the theory model of the virtual testing based on VR, the system framework of the virtual testing platform of vehicle vibration based on VR （VTPOVVBVR）, which consists of VR subsystem, modeling subsystem and VI subsystem, was proposed, and the implementation method of the VTPOVVBVR was studied. The three subsystems of the VTPOVVBVR were discussed, and the display of the virtual testing results of the vehicle vibration was presented, which shows that the vehicle vibration and its signals of time domain and frequency domain could be observed simultaneously in three observation models respectively by the aid of the platform.
