【摘要】 传统3D仿真技术系统缺少沉浸感、真实感和互动体验性。提出基于Unity3D引擎、HTC VIVE交互设备的VR(Vitual Reality虚拟现实)的仿真技术,给出在城市轨道交通车辆工程中仿真系统中的应用。进而给出了该仿真系统的硬件建设方案,仿真系统设计的整体框架和开发流程;讨论并研究了仿真系统中虚拟场景及实物的建模和车辆维修实时交互的关键技术。以维修中安装牵引电机螺帽为例,详细阐述了在Unity3D中采用C#编程实现虚拟人机交互功能的逻辑思路、操作过程和设计方法。更多还原

【Abstract】 Traditional 3 D simulation lacks immersion,authenticity and interactive experience. Based on the Unity3 D engine and the HTC VIVE interactive equipment VR( virtual Reality) simulation technology was applied in urban rail transit vehicle engineering. First,the hardware construction scheme of the simulation system and the overall framework,including the overall framework and development process of the simulation system design,was given. Next,the key technologies of virtual scene and physical object modeling and real-time interaction of vehicle maintenance was discussed. Finally,take the maintenance of traction motor nut as an example,the logical thinking,operation process and design method of virtual human-computer interaction which using C # programming to achieve in Unity3 D are elaborated.更多还原
