Multibody system dynamics is based on classical mechanics and its engineering applications ranging from mechanisms, gyroscopes, satellites and robots to biomechanics and vehicle engineering. Multibody systems dynamics is characterized by algorithms or formalisms, respectively, ready for computer implementation. The simulation of multibody systems demands for adequate dynamic models and takes into account various phenomena. Classical dynamics does not regard all nonlinear effects that appear as a result of the action of multibody systems, as well as their mutual interaction. The virtual prototyping and dynamic modeling of such systems are, from an economical point of view, perspective fields of scientific investigations having in mind the huge expenses for their design and manufacturing. Complex multibody systems composed of rigid and flexible bodies performing spatial motion and various complex tasks are up-to-date objects of virtual prototyping. As a result simulation and animation featuring virtual reality are most important. Recent research fields in multibody dynamics include standardization of data, coupling with CAD systems, parameter identification, real-time animation, contact and impact problems, extension to electronic and mechatronic systems, optimal system design, strength analysis and interaction with fluids. Further, there is a strong interest on multibody systems in analytical and numerical mathematics resulting in reduction methods for the rigorous treatment of simple models and special integration codes for Ordinary Differential Equation ODE and Differential Algebraic Equation DAE representations supporting the numerical efficiency. New software engineering tools with modular approaches improve the efficiency still required for the more demanding needs in biomechanics, robotics and vehicle dynamics.
