摘　　要：首先根据相贯线焊接仿真系统的功能对系统的总体结构进行了规划与设计。其次根据工艺参数和焊接过程中的运动特点进行了机械结构设计,使得焊枪能够根据需要进行灵活的运动。再次通过插补运算和工艺流程的设计实现焊接设备与工件的运动控制,从而兼顾运动的合理性与精确性。系统在MFC和OpenGL环境下开发,实现了对自动焊接和示教焊接过程的仿真,并能在示教焊接结束时进行实际轨迹与理论轨迹的对比。在OpenGL使用中采用轨迹球技术实现视角控制,并具备碰撞检测功能。The framework was planned and designed firstly according to the functions of intersection line welding simulating system.After that mechanical structure was designed according to prerequisite parameters and the movement features during the welding processes to make the welding torch achieve necessary movements flexibly.Then the motion control for welding equipment and workpiece was accomplished by interpolation arithmetic and the design of welding processes combining the rationality and accuracy of the motion.The system was developed under MFC and OpenGL and the simulations of both automatic welding and teaching/playback welding were achieved.Besides,the comparison of the theoretical track and real track was available after teaching/playback welding.Finally the trace ball technology was adopted to control the view angle by using OpenGL and collision detection was provided as well.
