Abstract: Based on multibody system dynamics method, the multibody system dynamics model of one vehicles crank and connecting rod mechanism was built, using Pro/E and ADAMS, the related problems were discussed, including the demand of model mass characteristic and the method of model transformation form Pro/E to ADAMS, flexible body of crankshaft establishment and transformation by using the PEM software ANSYS, the establishment of multibody system dynamics in ADAMS, etc. A foundation is given for research of the type.
Key words: crank and connecting rod mechanism; multibody system dynamics; ADAMS; model neutral file
