201 Multibody Dynamics Analysis in the Environment of FEM Preprocessor

Multibody Dynamics Simulation system in the environment of FEM was developed. Multibody Dynamics model can be created in the FEM preprocessor. The body properties such as center of gravity location, mass and inertia are able to be changed easily by the design parameters based on FEM meshes. This system allows the FEM users to apply multibody dynamics analysis in their familiar FEM environment. This paper shows an application of the developed system for single cylinder engine using the morphing technology for piston shape modification based on FEM mesh.
