Abstract EN
This paper compares the use of two impact simulation methods for two-degree-of-freedom nonlinear vibroimpact systems with rigid and soft impacts.
These methods are (I) impact simulation by boundary conditions with the use of Newton's restitution coefficient based on stereomechanic shock theory and (II) impact simulation by contact interaction force based on quasistatic Hertz's contact theory.
It is shown that both methods are applied and give the coinciding results for system with elastic rigid impact under periodic external loading.
Loading curves built by parameter continuation method are confirming this result.
Impact simulation by the second method is also fulfilled for vibroimpact system with rigid impact under random external loading.
For vibroimpact system with soft impact, the simulation of impact by the second method gives a better result.
The application of linear elastic force as contact one is possible too but the use of Hertz's contact force is more preferable.
The authors consider that the impact simulation by Hertz contact interaction force gives good results for nonlinear vibroimpact systems with impacts of any kind if all limitations with Hertz's law used are observed.
