Dynamic Characteristics Modeling for A MR Damper using Artifical Neural Network

인공신경망을 이용한 MR댐퍼의 동특성 모델링

  • Published : 2004.05.01


MR dampers show highly nonlinear and histeretic dynamic behavior. Therefore, for a vehicle dynamic simulation with MR dampers, this dynamic characteristics should be accurately reflected in the damper model. In this paper, an artificial neural network technique was developed for modeling MR dampers. This MR damper model was successfully verified through a random input forcing test. This MR damper model can be used for semi-active suspension vehicle dynamics and control simulations with practical accuracy.
