Content of Course

Machines, robots, vehicles and lightweight structures, that are subject to elastic deformation alongside large, non-linear working motions can be investigated using the method of flexible multibody systems. Significant examples are modern lightweight designs, rapid moving machine tools, robots and machinery with high precision requirements.

Firstly holonomic, rigid multibody systems in tree structure are recapitulated. After different approaches of modelling flexible multibody systems are introduced, the derivation of the floating frame of reference appraoch is explained in detail. This includes the kinematic description of elastic bodies, application of different shape functions to describe the elastic deformation, approaches for model reduction, the kinetics of a free body, its description using standard data, as well as a formalism to assemble the entire system.

Furthermore, the description of contact problems in multibody systems are presented. This includes continuous contact modelling and contact of flexible bodies. Finally, the further enlargement to the discrete-element-method is introduced.
