摘要:

本文针对HCW-90型全液压自动猫道的钻杆支架起升过程进行研究，采用多体动力学与液压控制系统联合仿真方法，分析了钻杆支架起升液压缸动作的同步性对钻杆从支架末端运动至平台档销限位处的动态过程的影响。重点讨论了起升液压缸同步性对管体空间位姿、动力学参数、管体运动至终了处与档销碰撞过程。进一步分析了管体受到限位后趋于稳定的动态过程和定位精度。此外，综合考虑管体运移的快速性、平稳性和定位准确性，对起升液压缸的液压控制系统的输入信号进行了合理调整，并在满足工作性能的前提下，提出了采用分流阀构建低成本液压控制系统的方案。

Abstract:

In this paper， the lifting process of the HCW-90 full hydraulic automatic catwalk drill pipe bracket is studied， and the influence of the synchronicity of the lifting hydraulic cylinder action on the movement of the drill pipe from the end of the bracket to the limit of the platform pin is analyzed by using the co-simulation method of multi-body dynamics and hydraulic control system. The effect of the synchronicity of the lifting hydraulic cylinder on the position and attitude of the pipe body， the dynamic parameters and the collision process between the pipe body and the stop pin at the end of the movement are discussed. The dynamic process and positioning accuracy of the pipe body tending to stability after being limited are also analyzed. In addition， considering the rapidity， stability and positioning accuracy of pipe transfer， the input signal of the hydraulic control system of the hoisting hydraulic cylinder has been properly adjusted， and under the premise of satisfying the working performance， the scheme of constructing the low-cost hydraulic control system by diverting valve is put forward.
