水平定向钻进虚拟仿真培训系统研究

Research on virtual simulation training system for HDD

摘要:

虚拟仿真技术是目前计算机科学研究热点，将虚拟仿真技术应用到非开挖领域是非开挖教学及研究的发展趋势。针对水平定向钻进（Horizontal Directional Drilling，HDD）这一非开挖的主要施工工法，采用SolidWorks、3ds MAX、Photoshop等软件对三维场景、钻机以及钻头等施工设备进行三维建模，通过研究场景漫游技术、多摄像机跟随技术、物理效应仿真技术和轨迹记录及跟随等技术在Unity3D平台上开发培训系统，并将系统发布至桌面系统。该系统具有场景漫游、多视角显示、控制钻进、显示参数功能。测试结果表明培训系统运行流畅，场景切换迅速，具有良好的三维展示和教学功能。

Abstract:

Virtual simulation technology is a hot topic in computer science research currently, and applying it to trenchless pipe laying is the development trend of teaching and research. Since HDD is the main construction method of trenchless technology, SolidWorks, 3ds MAX, Photoshop and other software were used to set up a 3D model for the 3D working scenario, drill rigs, drill bits, etc. The training system was developed on the Unity 3D platform by researching scene roaming technology, multi-camera following technology, physical effect simulation technology, track record and follow-up technology etc. and the system was released to the desktop system. The system includes scene roaming, multi-view display, control drilling and display parameter. The test results show that the training system runs smoothly, the scene switches quickly, and has a good 3D display and teaching functions.
