MR댐퍼를 부착한 운전석의 진동특성 시험

The traditional seat has a passive damper and an air spring in its suspension. In this study, a MR damper is developed to improve the ride comfort of the seat. MR damper uses MR(Magnetorheological) fluid, which is a smart material that can change its rheological property when magnetic fields are applied. The vibration attenuation performance was tested for both seat with the MR damper and the passive damper using a seat simulator. Then, both results were compared to confirm the improved performance of the seat with the MR damper.
