Özet
This paper investigates the performance of fuzzy logic controlled active suspensions on a six-degree-of-freedom rail vehicle model. The vibration control of rail vehicle body and passenger seat is especially important for comfortable travel under high speed. To obtain essential performance requirements for comfort level for the users, a Fuzzy Logic Controller (FLC) is designed. FLC is preferred because of its robust character and superior performance in active vibration control. This vehicle is modeled as a lumped parameter system which consists of a body, bogie, primary and secondary suspension and rigid wheels. The model has been designed to take into account the complexity of wheel-rail contact. Therefore, an adaptive contact model is used for the representation of contact force. This contact model is linearised with the Hertzian spring. At the end of the study, time history and frequency response for accelerations and displacements of the rail vehicle, are presented for the uncontrolled and controlled systems. Performance and advantage of the suggested approach are discussed.
