摘要:
针对石油钻采专用阀门内壁复杂曲面的自动堆焊,在堆焊设备的研发过程中,建立了阀门内壁相贯曲线的数学模型,规划了堆焊焊枪的运动轨迹.在Pro/E软件工作环境下,建立了堆焊设备的三维实体模型,定义了运动连接,设定了伺服电机参数,进行了堆焊设备虚拟样机的计算机运动仿真试验,通过仿真分析,生成了运动轨迹曲线并进行了仿真误差分析,验证了该数学模型建立的正确性,为堆焊设备的研制提供了相应的虚拟样机仿真技术支撑.

Abstract:
In the development process of automatic welding equipment which is used for the complex inner surface welding in petroleum drill special-purpose valve,the mathematic model of valve inner surface intersection curve was modeled,and the motion trajectory of welding gun was planned.The 3D model of the welding equipment based on Pro/Engineer working environment was established,the definition of the motion jointing and the parameters of servo motors were set,the virtual prototype motion simulation experiment of the welding equipment was run,the motion trajectory curve was created,and the simulation errors was analyzed.The correctness of modeling the mathematic model was validated,which provided the simulation technology supporting of virtual prototype for developing and manufacturing the welding equipment.
Key words:  petroleum drill valve  intersection surface  motion simulation  trajectory curve
