Synchronization in impact winning machines
- 17 Downloads
Synchronization of the natural vibration frequency with the frequency of impact perturbation in an impact winning machine leads to a reduction in vibration amplitude and it provides a constant backing force for the bit on the face.
Synchronization is achieved by selecting the appropriate impact amplitude or frequency.
Synchronization conditions obtained for an impact winning machine may be used to calculate parameters for individual strikers with an elastic suspension arm on the machine.
