Abstract: This paper aims to evaluate the effectiveness of the centrifugal pendulum applied to an internal combustion engine as vibration damper. In particular, a specific design strategy, based on an energy equivalence, is analysed using a series of multibody simulations. A simplified model is initially discussed and different solution morphologies simulated. The present solution is based on the roller-in-slot centrifugal pendulum, designed to have the same kinematic behaviour of lumped mass models. The reasons why the centrifugal pendulum has had in recent years numerous applications are evidenced, together with a discussion of some design strategies. The main characteristics and requirements of this vibration damper are presented. Simulation strategy is subsequently showed, with a description of all bodies, forces and parameters used in the different systems analysed. To assess the effectiveness of the design strategy, a comparison among the simulation results of the different solutions is offered.
