Dynamic Vibration Absorber for Friction Induced Oscillations
- 1.2k Downloads
Friction induced vibrations in technical applications are usually unwanted, as they create noise, diminish accuracy and increase wear. By this article the authors intend to give an insight in basic excitation mechanisms of friction induced vibrations and to show possible ways of avoidance. A dynamic vibration absorber is investigated in detail. Numerical and experimental results show that stick-slip vibrations can be avoided or at least reduced considerably by an additional spring-mass-damper system attached to the main oscillator.
