Mehrkörpersimulation

What it is about

You learn to describe and numerically simulate mechanical multibody systems consisting of rigid and flexible bodies. In the end you will derive motion differential equations for planar and spatial systems, embed flexible FEM bodies into multibody systems, and apply numerical time integration methods for linear and nonlinear systems with constraints.

What you will be able to do

• Describe a mechanical system as a classical multibody model
• Apply modular formalism to derive the equations of motion
• Master relative kinematics in three dimensions and rigid-body dynamics
• Embed flexible bodies from FEM into multibody systems
• Use numerical time integration methods for linear and nonlinear systems with constraints

What the module consists of

• VorlesungConveying the mathematical relationships and derivations; presentations and script as teaching materials
• Demonstrationen / BeispieleNumerical implementation on simple example systems for deepening understanding
• Physische Lehrmodelle (wenn möglich)Illustrating spatial rotations and kinematic relationships

Teaching method

• Präsentation (Tablet-PC)Step-by-step derivation of complex relationships and discussion of their meaning for multibody simulation
• Vorlesungsfolien und SkriptSupport for preparation and review
• Matlab-Beispiele, Animationen/Visualisierungen, FallbeispielePractical implementation, visualization and practice of the methods
