The stability of the PK-3 heading machine


  1. 1.

    The vibration of the PK-3 heading machine when its cutting head (with stationary bit) interacts with the face is represented by a differential equation, the solution of which was obtained with allowance for the action of the hydraulic drive.

  2. 2.

    The experimental results on the variability agree with the theoretical predictions of the formation of vibrations of the machine along the line of motion owing to the action of the hydraulic drive.

  3. 3.

    Problems of the stability of PK-3 machines in space can be solved by taking account of the influence of the action of the cutting head on the vibrating system of the machine plus the hydraulic drive.
