MBD is particularly suited to analyse complex systems with multiple degrees of freedom.  Examples are cars, trucks, railways, roller coasters, and household appliances. Using MBD, several aspects of those applications, such as safety, performance, and comfort, can be evaluated and optimised. We apply MBD to model both the kinematics and the dynamics of moving systems. This enables our engineers to calculate and visualise the movements and forces resulting from external excitations. With this information the dynamical behaviour of an application can be optimised effectively.
