Abstract

Symbolic formula manipulation has proven to be an efficient tool in the dynamical analysis of multibody systems. A multibody system data base is introduced and its implementation using a CAD-3D-software is shown. Starting from the data base the equations of motion are generated by a coordinate partitioning approach combined with the projection criterion. For the symbolical-numerical solution inverse kinematics algorithms are applied. The simulation results are visualized by computer animation. A four-bar mechanism and a crank-slider mechanism serve as examples. Two approaches for the dynamical analysis of flexible multibody systems are presented. Further, the optimization of multibody systems is treated using an actively controlled vehicle suspension as an example.KeywordsMultibody SystemInverse KinematicMulti Body SystemFlexible Multibody SystemCrank Slider MechanismThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
