Keywords: dynamic vibration absorber, torsional vibration, quadratic torque method


This paper presents an analytical method to determine optimal parameters of the dynamic vibration absorber (DVA, a type of the CPVA), such as the ratio between natural frequency of DVA and shaft, the ratio of the viscous coefficient of absorbers. The theoretical method was established using minimum of quadratic torque (MQT). First, the original model presented by Warbuton will be solved. The results showed a good agreement. Then, this analytical method is used for torsional shaft model. The simulation results indicate that the effectiveness in torsional vibration reduction. The optimal parameters of DVA were then applied to reduce the shaft torsional vibration with consideration for the vibration duration and stability criterion.
