摘　　要：提出了采用月球探测车探测月球的总体构想 ,其特点是将虚拟现实技术引入其中。着重讨论了运用虚拟现实技术进行月球探测车地面模拟和仿真的方法 ,对月球探测车虚拟环境系统的生成、虚拟月球地形地貌的创建、虚拟月球探测车、动力学仿真、建模与仿真的校核、验证和确认进行了论述。为了验证提出的月球探测车地面模拟与仿真虚拟现实技术方法的可行性和有效性 ,已经建立了虚拟月球环境的平台 ,设计了虚拟月球探测车模型 。A general imagination for using lunar exploration vehicle to explore the moon, which features virtual reality technology, is put forward in this paper. The methods of applying virtual reality technology to the simulation of lunar exploration vehicle are discussed. Building of virtual environment for moon exploration, establishment of virtual lunar terrain, virtual lunar exploration vehicle, dynamic simulation and verification, validation and accreditation for modeling and simulation are described. The platform of lunar virtual environment and the model of virtual lunar exploring vehicle are built in order to demonstrate the rationality and validity of the methods, and the problem of dynamic simulation in lunar environment has been solved.
