摘　　要：为减小BTA深孔钻削加工过程中钻杆振动对刀具寿命和工件加工精度的影响,开发了一种钻杆振动主动控制系统。所设计的超磁致作动器(GMA)能够满足钻削振动高频响和高精度的控制要求。在系统总体设计的基础上分别对钻杆振动模型和作动器动力学特性进行了分析,建立了传递函数模型。利用MATLAB软件对PID算法控制系统进行仿真,最终通过实验验证了所设计的振动主动控制系统对钻杆振动抑制的有效性。A system of drill active vibration control is developed to solve the tool life and workpiece machining pre- cision problem caused by BTA deep drilling process vibration. The giant magnetostrictive actuator （GMA） designed can satisfy high vibration frequency response and precision control requirements in drilling. The transfer function model of drill pipe and the vibration actuator dynamics models are ana- lyzed separately. Uses MATLAB software to simulate the control system of PID algorithms, then the ac- tive vibration control system is tested through experiments. Finally, the results show that the controller can suppress the vibration of drill pipe effectively.
