摘要 侧墙是高速列车车体的主要构成部分,由于其焊接工艺复杂、专业设备昂贵,因此企业需要不断培养技术熟练的员工来满足生产要求,但常规的人员现场培训方法会占用专业的生产设备,降低企业生产效率,难以达到良好的培训效果。为了满足企业对专业焊接人才培养及培训的需要,基于虚拟现实技术,通过3dsMax建立焊接车间及装卡工具模型,采用LOD技术降低内存占用。依靠Unity3D虚拟现实引擎搭建仿真环境,采用C#编程语言开发系统功能,并应用包围盒算法优化焊接过程演示。参照铝合金侧墙焊接工艺流程,开发完成高速列车侧墙焊接虚拟现实系统。实践表明,所开发的系统包含知识考核、操作交互、结果展示等功能,具有较好的实用性、可视性及沉浸感,能够有效满足高速列车制造人员训练要求,同时保证培训期间企业生产效率,降低了事故发生的概率。 The side wall is the main component of the high-speed train body.Due to its complex welding process and expensive professional equipment,enterprises need to continuously cultivate skilled employees to meet production requirements.However,conventional on-site personnel training methods occupy professional production equipment,reduce enterprise production efficiency,and it is difficult to achieve good training results.In order to meet the needs of enterprises for the cultivation and training of professional welding personnel,based on virtual reality technology,a welding workshop and card loading tool model are established through 3ds Max,and LOD technology is used to reduce memory usage.Relying on the Unity3D virtual reality engine to build a simulation environment,using C#programming language to develop system functions,and applying bounding box algorithm to optimize the welding process demonstration.Based on the welding process of aluminum alloy side walls,a virtual reality system for high-speed train side wall welding is developed and completed.Practice shows that the developed system includes functions such as knowledge assessment,operation interaction,and result display,which has good practicality,visibility,and immersion.It can effectively meet the training requirements of high-speed train manufacturing personnel,while ensuring the production efficiency of the enterprise during the training period and reducing the occurrence of accidents.
