Abstract

Flexible multibody systems feature a coupled mathematical model with ODEs or DAEs governing the gross motion and PDEs describing the elastic deformation of particular bodies. Frequently, semidiscretization of elastic membersleads to a stiff mechanical system with widely different time scales. Thispaper investigates the behavior of numerical time integration methods at flexible multibody systems and gives some recommendations. Simulation results for a slider crank mechanism and a truck model illustrate what can go wrong and how implicit methods like RADAU5 can be effectively applied.
