Abstract

This paper presented a combined theoretical and experimental design methods to determine optimal parameters of a centrifugal pendulum vibration absorber (CPVAs), such as spring stiffness, damper oil viscosity, moment of uinertia of the system components, number of absorbers and assembly position. First, the system of equations of motion of the CPVA was established and solved using Finite Element method (FEM) and Runge-Kutta algorithm (RKA). Then, the optimal design based on Taguchi method was carried out to find optimal parameters of the CPVA with consideration for the torsional vibration duration and stability criterion. The numerical results showed that torsional vibration of the CPVA is remarkably reduced with using the derived optimal parameters.
