Hertz contact model based on the flexible beam vibration analysis of the collision
Vibration generated in the same direction. 2. When the excitation frequency away from the match condition, the coupled modal solution increases, the collision point of contact at this time the reverse happened vibration, impact strength of a larger, system performance, a typical nonlinear. 3. Big to small changes in tuning parameters, under the beam vibration amplitude changes slowly, the system for single-mode approximation of movement. 4. Collision damping of small amplitude has little effect on the system,mulberry taske, the collision radius of curvature of the phase shift of the first magnitude greater impact on relatively flat under the beam affected. 5. Multi-modal solution caused changes in response to jump on the excitation intensity of the phenomenon.
