摘　　要：研究了基于虚拟现实的虚拟测试技术的概念和理论模型。根据车辆振动测试系统与基于虚拟现实的车辆振动虚拟测试系统之间的映射关系,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虚拟现实的车辆振动虚拟测试系统的框架设计及实现方法。设计了基于虚拟现实的车辆振动虚拟测试系统,并给出了车辆振动的虚拟测试结果显示,结果表明:基于虚拟现实的虚拟测试技术的理论模型适用于基于虚拟现实的车辆振动虚拟测试系统设计,通过该系统,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。The concept and the theory model of the virtual testing based on virtual reality are studied. In terms of the mapping relation between the vehicle vibration testing system and the virtual testing system of vehicle vibration based on virtual reality （VTSVVBVR）, the system framework design and the implementation method of the VTSVVBVR, which consists of virtual reality subsystem, modeling subsystem and virtual in- strument subsystem, are proposed. The VTSVVBVR is designed, and the display of the virtual testing results of the vehicle vibration is presented, which has shown that the theory model of the virtual testing based on virtual reality is suitable for the VTSVVBVR design, and 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 system.
