基于VR技术的CHR1转向架虚拟装配研究

Virtual Assembly for High-Speed Bogie of CHR1 Using VR

为探讨虚拟装配技术在高速转向架设计、制造、检修中的作用,阐述了虚拟现实系统的开发流程,并针对CHR1转向架,使用SolidWorks建立了零件的三维模型,然后将三维模型导入3D Max中,进行渲染、材质、灯光等处理,并导出Nmo格式的文件,最后将Nmo文件导入Virtools,编写脚本程序,完成了CHR1转向架的虚拟装配平台的开发。在平台中,可以从任何角度和任何位置观察转向架构造;可以按照既定的装配顺序,采用点击或拖动方式完成CHR1转向架的虚拟装配过程。研究表明,虚拟装配技术对提高产品设计生产并行性、降低产品生产成本、减少产品上市时间、产品展示和培训检修人员技能等都具有较为重要意义。

The development process of virtual reality systems in high-speed bogie design,manufacture,maintenance is discussed,and the 3D model of CHR1 is established using the SolidWorks software,and then the 3D model is imported into 3D max software and is rendered,textured,and lighted in it and is exported to files with nmo format,and finally the nmo files are imported into Virtools software and the program is made in it to implement the virtual assembly platform of CHR1 bogie.In the platform,CHR1 bogie can be viewed from any angle and any position and can be assembled in accordance sequence with a clicking or dragging way.It seems that,concurrent design capability can be improved and production costs and time to market can be reduced with virtual assembly.
