【Abstract】 The united computation model of unbranched system and branched system has been built based on the expanded transfer matrix, which can be used to analyse the torsional vibration of vehicle driveline. Making use of the platform in Matlab, the analysis software has been built. The key technologies of free vibration and forced vibration analysis have been depicted. And the united numerical computation method for unbranched system and branched system has been depicted based on the expanded transfer matrix. Finally, the software has been tested with two instances of the driveline of one vehicle, and the results show that the software is effective and efficient.更多还原
