Abstract

Impact dampers are passive devices used to attenuate vibrations by means of momentum transfer and dissipation of energy. This paper deals with investigations carried out to evaluate the damping ratio of an impact damper system for case without and with impact ball of same size made of different materials. Finite element modelling of the system is carried out using ANSYS FEA (finite element analysis) software. Simulation studies are carried out using Augmented Lagrangian Multiplier (ALM) contact algorithm to obtain the transient response of the system. The transient response of the system is evaluated from the forces generated due to impact of ball on the primary system. Theoretical studies are carried out with impact mass placed at tip of cantilever beam by varying base excitation frequency in vicinity of systems fundamental frequency to obtain the frequency response curve. The response curves thus obtained with impact mass made of different materials show that damping achieved with higher impact mass is very effective in attenuating the vibration response. Results from simulation studies show good agreement with experimental data. The effect of damping with different mass ratio is also investigated.
