磁流变阻尼器建模及在座椅减振中应用
MRD Modeling and Its Application in Seat Cushioning
摘要
Abstract
The vehicle seat system has an important impact on the car ride comfort.Using the controllable damping characteristics of the magnetorheological damper (MRD) can effectively reduce the vibration of the vehicles.In this paper,the damping characteristic of the MRD of the seat system is tested,and the parameters of the Bouc-Wen model of the MRD are identified by using genetic algorithm.Through analyzing the loading condition of the single DOF seat system,the single DOF dynamic model of the seat suspension system is established and the semi-active control system of the roof switch for the seat MRD semi-active suspension is designed and simulated.The result shows that the parameters and the model identified by using genetic algorithms can meet the requirements.After using the magnetorheological semi-active seat suspension,the seat acceleration peak is reduced by 17.4 ％,the seat acceleration mean square root is reduced by 13.1％.Automobile ride comfort is significantly improved.关键词
