Abstract EN
The impact between a rotating link and a solid flat surface is considered.
For the impact, we consider three distinct periods: elastic period, elastoplastic period, and restitution period.
A Hertzian contact force is considered for the elastic period.
Nonlinear contact forces developed from finite element analysis are used for the remaining two phases.
The tangential effect is taken into account considering a friction force that combines the Coulomb dry friction model and a viscous friction function of velocity.
Simulations results are obtained for different friction parameters.
An experimental setup was designed to measure the contact time during impact.
The experimental and simulation results are compared for different lengths of the link.
