The four parts of the book - nonlinear multibody dynamics, virtual multibody systems, control design and mechatronics, and challenging applications - describe the status of multibody dynamics, with special emphasis on nonlinear systems, virtual reality and control designs required in mechanics and other applications. Other topics include: nonholonomic systems, flexible multibody systems, contact, impact and collision, numerical methods of differential-algebraic equations, simulation approaches, virtual modelling, mechatronic design, control, biomechanics, space structures and vehicle dynamics.
