After the course, the student is able to:
- Perform a kinematic analysis on flexible multibody system: Choose degrees of freedom; formulate constraint equations; solve position, velocity and acceleration equations.
- Perform a dynamic analysis: Derive the equations of motions using the Principle of Virtual Work. Formulate these equations in Lagrange multiplier form or in minimal coordinate form with equations of reaction*.
- Explain how flexibility of individual bodies can be taken into account in a multibody formulation using theory of linear elasticity and model order reduction techniques such as the Craig-Bampton method, as well as using deformations of the finite elements.

The field of flexible multibody dynamics is concerned with the study of the dynamic behaviour of mechanical systems that consists of multiple flexible bodies that are connected together by joints. In this course, state of the art methods with which the dynamics of such complex systems can be analysed are presented. As a final assignment, students are asked to apply the theory of dynamics, as presented in lectures, on a realistic spatial flexible multibody system of their own interest. This final assignment is performed in groups. Examination is based on an individual written exam about the theory. Admission to the written exam is only gained when a presentation about their final assignment is of sufficient quality.
