| 英文摘要: |
| The robotic drilling always generates the axial vibration along the drill bit and the torsional vibration around the drill bit, which will adversely affect the drilling precision. A vibration control mechanism fixed between the end-effector and the robot is proposed, which can suppress the axial and torsional vibrations based on the principle of vibro-impact (VI) damping. The energy dissipation of the system by vibro-impact damping is analyzed.Then, the influence of the structure parameters on the vibration attenuation effect is studied, and a semi-active vibration control method of variable collision clearance is presented.The simulation results show that the control method has effective vibration control performance. |
