Abstract: | In this paper, the dynamics of a vibrator-controlled adaptive damper is simulated. Its potential in vehicle isolation improvement is demonstrated by a quarter car model. From the results obtained, it is known that after adding a vibrator-controlled flow valve to the conventional hydraulic damper, it is possible to achieve a desired frequency-dependent damping characteristics to provide a large damping at system resonance for the attenuation of the system resonant overshoot, but small damping at higher frequencies to guarantee a good isolation performance. The special feature of this adaptive damper lies in the fact that the damper can be constructed totally mechanically without electronics, which provides a practical way for industrial applications. |
