摘  要：基于当今民航维修业发展趋势，顺应大环境下互联网技术的发展模式，开发了以用户为中心的人性化、智能化的维修教学系统，采用计算机仿真與虚拟现实技术，帮助用户完成复杂的维修工作。以Unity 3D为集成开发平台为基础，通过Solidworks、3DMax、C4D等对于场景中的机械以及人物进行建模，对发动机维修实习车间、车间教学课堂等真实场景进行高度虚拟化的还原;利用Visual Studio编辑器结合C#语言对内置模型实现可交互式逻辑编程，对于零件间的维修特征、对象行为以及虚拟人行为等交互特征进行参数化描述，最终以Xsens MVN和PUN实现异地交互的虚拟现实功能。

Abstract： Based on the development trend of civil aviation maintenance industry and the development mode of Internet technology under the environment， the system has developed a user-centered humanized and intelligent maintenance teaching system， which adopts computer simulation and virtual reality technology to help users complete complex maintenance work. Based on Unity 3D integrated development platform， the machine and characters in the scene are modeled by SolidWorks， 3DMax and C4D， and the real scenes such as engine maintenance practice workshop and workshop teaching classroom are restored with high virtualization. Visual Studio editor combined with C# language is used to realize interactive logic programming for the built-in model， and parameterized description is carried out for the interaction features such as maintenance features between parts， object behavior and virtual human behavior. Finally， XsensMVN and PUN are used to realize the virtual reality function of remote interaction.

Key Words： Virtual reality; Remote interaction; multi-person cooperative; Maintenance

在航空航天领域，普遍存在使用设备成本高、技术难度大、维修技术人员培训周期长、硬件损坏不可逆等问题。诸多因素困扰了研发、使用、维修等诸多环节的研究和培训进度，又因其突出存在的不可逆性限制了航空的发展和进步。在当今疫情严峻的形势下，民航行业运营情况持续低迷，维修技术人员的培训出现了诸多不利条件。但是，由于市场对技术人才的需求并未停止，迫切需要一种成本低、培训周期短、可逆性强的解决方案来弥补这项漏洞，辅助用户完成复杂的维修装配工作，切实提高作业效率和准确度，切实利用互联网技术所提供的便利条件，完善机务维修人员培养模式，提高人员质量。……
