Application of collaborative simulation based on interfaces for dynamic properties of an engine's mechanical system

摘要

The collaborative simulation based on interfaces is an effective method for dynamic property analysis of a mechanical system. It includes multibody system dynamics analysis and finite element structural dynamics analysis, both of which are based on geometry modeling. In this paper, Pro/E is applied to build the geometry models, ADAMS is applied in the multibody system dynamics analysis, and ANSYS is applied in the finite element structural analysis. The data exchange and collaborative simulation process based on their interfaces are presented in this paper. As to one V-type 8-cylinder engine's mechanical system, the geometry model of the overall system, the multibody system model of the mechanisms, and the finite element model of the block are built, thus the kinematics and dynamics properties and structural dynamics responses are predicted.
