Mathematical modelling and simulation of epicycloidal path type centrifugal pendulum vibration absorber applied on three-staged stiffness clutch damper

Abstract

The concept of epicycloidal pendulum is introduced based on definition of involute. The equations of motion of epicycloidal path type centrifugal pendulum vibration absorber (CPVA) are derived, with which a simulation model of tautochronic epicycloidal path type CPVA is established. Some numerical simulations are done to investigate the characteristic of the natural frequency of tautochronic epicycloidal path type CPVA, to analyse effects of tuning order and pendulum motion amplitude on its performance and to contrast the performance between tautochronic epicycloidal and circular path type CPVA. The performance of three-staged stiffness clutch damper with tautochronic CPVA under creeping condition is also investigated.
