Design of virtual training system for core drill based on Unity3D

摘要: 大型岩心钻机价格昂贵、操作工序复杂且十分危险，导致传统的培训技术难以高产出操作纯熟的技术人员，同时传统的培训技术以理论学习与直接上机相结合，如此跨越式培训增加了岩心钻机损坏与报废的风险，也提高了培训者自身门槛。基于此，提出了基于Unity3D的岩心钻机虚拟实训系统设计方案，并以XY-4型岩心钻机为例，采用SolidWorks与Maya联合建模、Unity3D进行软件系统开发。Unity3D可模拟出真实工作场景，让系统使用者有身临其境的感觉。实训系统设置4个学习场景：认知视频学习、操作要领学习、单步训练以及整体训练，操作知识环环相扣，人与场景融为一体。Abstract: Large-scale core drill is expensive, complicated in operation and dangerous to manipulators, leading to the difficulty in traditional training techniques for skilled technicians. What's more, the leap type of traditional training of theoretical learning and practice on-board increases the risk of rig damage and scrap, also raises the threshold of trainers. Therefore, this paper proposes a design scheme of core drill training system based on Unity3D, and taking XY-4 core drill as an example, which is modeling by SolidWorks and Maya. The software system is developed with Unity3D, which is able to simulate real-life work scenarios, and gives system users an immersive feeling. The training system sets up four learning scenarios: cognitive video learning, operational essentials learning, single-step training, and overall training. In this system, operational knowledge is interlocked, with people and scenes blended together.
