The optimum of impact parameters on tuning mass damper with plastic impact

Abstract：The mechanics model of control system, which has tuned mass damper (TMD) with impact, and the dimensionless equations of two-degree system are derived.The approximate solution of the system is derived by using the synchronization character of the solution of the TMD with plastic impact under the harmonic oscillation, and the sensitivity of the impact parameters are analyzed with numerical simulation.The results show that the parameters of clearance and restitution coefficient are more sensitive for the TMD system with impact.In a given system, the optimum clearance and the optimum coefficient of restitution are exist.The TMD can hold good control effective under collision when the impact parameters are suitably selected.
