Underwater beveling machine processing kinematics analysis

坡口机是海底输油管道维修的必需工具,它可以在水下或其它环境较恶劣的现场进行工作.根据其作业过程借助车铣原理建立了坡口机的运动学模型,针对坡口机的切削特点分别对径向进给运动、周向进给运动和径、周向合成铣削运动进行分析和探讨,并进行仿真验证.通过对仿真曲线分析得出了切削过程中各运动参数的关系,切削时运动参数选择原则以及实际工作可选择的切削方法.分析结果为实际坡口机的动力学分析和控制系统设计奠定基础.

The beveling machine is a necessary tool for repairing undersea oil and gas pipes. It can work under water and in other bad environments. Aiming at the milling process of the beveling machine, the kinematics was set up by using turn-milling theory. Taking beveling characteristics into account, kinematics analysis of the beveling machine with radial directional feed, circumference directional feed and resultant feed movement, was discussed in detail. The conclusion was validated by simulation. On the bases of analyzing simulated curves, the relationship of kinematics parameters were determined, principles of milling parameters were chosen, optimal milling methods and other aspects related to real-life work were analzyed work. These lay a foundation for dynamic analysis and control system design.
