The dynamic characteristics and damping mechanism of impact-contact between tips of blades were studied. The model of elastic impact forces for the impact-contact between tips of blades was established by employing the theory of elasticity. Then the impact-contact of blades was simulated numerically and the results were verified by experiments. Finally the nonlinear response characteristics and damping mechanism of impact-contact system were obtained.
