Abstract

Inherent nonlinear dynamic characteristic of vehicle system make vibration control quite complex and difficult. At the basis of analysis nonlinear single degree freedom model, a new strategy which combines semiactive control method and fuzzy control method is put forward. In the model, new fashioned MR damper is taken and detailed control rule and fuzzy system is established. Further more, to verify the efficacy of semiactive fuzzy control strategy, a 21 degrees freedom nonlinear model of locomotive with dampers is studied and a number of numerical simulations are made. The simulation results show that compared with passive control, the semiactive fuzzy control strategy can attenuate lateral vibration effectively and enhance critical velocity obviously to restrain snaking motion and digression accident.
