Multi- Universal Coupling Phase Modeling and Optimization Base on Floor Vibration Control

Torsional vibration of drive shaft has a great influence on the floor vibration, Rational arrangement of phase of multi-universal coupling can attenuate vibration. Accord to the vibration of the floor of one light bus, theoretical model has been established and Optimization program has been operated .The results of test validation and simulation show that the optimization scheme is effective and reasonable.
