BCP - A Benchmark for Teaching Structural Dynamical Systems

Abstract

AbstractNew object-oriented modelling techniques for physical systems along with more complex systems of interest lead to increasing requirements on modern simulators regarding performance and stability as well as state event modelling and event handling in combination with hybrid and structural dynamic systems. To see how modelling and simulation environments deal with such systems and to compare new approaches to hybrid modelling, a new benchmark is defined using three case studies with modelling and simulation tasks. The first case study investigates the classic bouncing ball example with some extensions. The second example discusses an electrical circuit - it can be used to compare the simulation results of different implementation techniques (e.g. physical modelling vs. classical DAE form) in one simulator. The third case study is a definition of a pendulum on a rope with free falling phase, representing another simple structural dynamic mechanical system. These three parts offer a spectrum of questions for testing basic features for handling hybrid and structural dynamic physical systems and they represent minimum requirements on hybrid simulators regarding state events.
