Abstract

Modeling of multibody mechanics plays a central role in the design of mechatronic systems. In technical use-cases; they often contain loose couplings; where contact is possible. We present a ready-to-use contact library in Modelica. It comprises surface definitions for simple contact surfaces; which can be connected with multibodies of the Modelica Standard Library. It implements a force-based approach between single contact points. The contact forces are calculated in configurable non-central contact blocks. Exemplarily; the results of three experiments are shown and compared to benchmark simulations.

Keywords

Contact library; simple contact surfaces; non-central contact block; contact forces
