Dynamics of Mechanical Systems with Soft Impacts
- 1.4k Downloads
Rigid impacts are described by the Newton elementary theory with coefficient of restitution. Different models of elastic and dissipative forces during the contact of impacting bodies should be assumed in the investigation of the motion of the oscillators with soft impacts, when impact duration cannot be neglected. This approach allows also understand the dynamics of mechanical systems, when the contact stiffness of impacting bodies changes from zero, corresponding to the impact-less motion, to infinity, which corresponds to the motion with rigid impacts.
