Event Details

Seminar of the “Multibody System Dynamics” collaborative class, in collaboration with the Warsaw University of Technology.

The simulation of contacts in large complex mechanical systems is an open problem in the multibody community. Among the most prominent approaches, we will discuss the method based on non-smooth contact dynamics.In this context, unilateral contact forces and frictional forces are defined via set-valued functions. This has the benefit of embedding discontinuous phenomena such as stick-slip and impacts directly in the formulation, although this comes at the cost of a more intricate mathematical framework, where Differential Algebraic Equations, typical of multibody systems, are extended to become Differential Variational Inequalities. In some literature, this is also called the Measure Differential Inclusion approach.Details will be discussed also about collision detection algorithms, parallel implementation and real-time applications.
