摘　　要：针对自动钻机给进位置控制精度低,影响自动上扣和卸扣成功率,进而影响自动钻机全自动施工流畅性的问题,利用AMESim建立自动钻机给进位置伺服系统动态仿真模型,详细介绍模型参数设置方法,并通过仿真结果验证模型的正确性。然后采用控制变量法仿真分析各器件和参数对给进位置伺服系统动态误差的影响程度,并根据仿真结果、综合成本与实施可行性,优化伺服系统液压与电控设计参数,提高自动钻机给进位置控制精度。最后在神东煤炭集团石圪台煤矿进行了现场试验,结果表明:优化后的自动钻机自动上扣和卸扣成功率由之前的92%提高到了98%,极大地提高了自动钻机全自动施工流畅性。In view of the low control accuracy of the feeding position of the automatic drilling rig,which affects the success rate of automatic make-up and unloading,and then affects the automatic construction smoothness of the automatic drilling rig,the dynamic simulation model of automatic drilling rig feed position servo system was established by AMESim,the parameter setting method of the model was introduced in detail,and the correctness of the model was verified by the simulation results.Then,the control variable method was used to simulate and analyze the influence of various components and parameters on the dynamic error of the feed position servo system,and according to the simulation results,comprehensive cost and implementation feasibility,the hydraulic and electronic control design parameters of the servo system were optimized to improve the control accuracy of automatic drilling rig feed position.Finally,a field test was carried out in Shigetai coal mine of Shendong Coal Group.The results show that the optimized automatic drilling rig s automatic make-up and unloading success rate increase from 92%to 98%,which greatly improves the automatic drilling rig s automatic construction smoothness.
