For inheriting the dynamic constraint information of the multibody simulation model, topological configuration of the multibody simulation model was built, and simplified constraint form was put forward with the topological mapping of the multibody simulation model in the heterogeneous systems. To transform the information of the multibody simulation model, the offset matrix which transformed the location and orientation of constraints and the matrix which transformed the location and orientation of parts were computed.
