Energy analysis and experimental evaluation of momentum exchange impact damper with pre-straining spring mechanism

ABSTRACT

The aim of this research is to evaluate the performance of impact-induced vibration control using momentum exchange impact damper with pre-straining spring mechanism (PSMEID) based on the energy analysis and verifying the effectiveness of the proposed method experimentally using a simple three-body collision model. It is shown from the simulation study that the fraction of energy absorbed by the primary mass was small if the excitation frequency differs from the primary mass natural frequency. In the case of excitation frequency is lower than the primary mass natural frequency, most of the impact energy is transferred to the damper mass. For excitation frequencies higher than the primary mass natural frequency, a large amount of impact energy is reflected after the collision. The energy absorption ratio is small if the damper mass ratio(M_d/M_p) approaches 0.2 and the ratio between pin force (f_pin)and the reference friction force (f_fref) closest to 1. The optimum condition of the pre-straining spring stiffness increases when the impact damper mass ratio is increased. The experiment was conducted to validate the simulation results. The experimental data has shown that the minimum acceleration response is obtained using the pre-straining spring deflection ratio (x_ps/x_psref  = 0.18).
