Abstract

The original damping skyhook (SK) vibration control method needs to determine the absolute velocity of the sprung mass, however, the absolute velocity is impossible to measure for a running vehicle. The modified damping skyhook method (MSK) instead uses the derivation of acceleration of the sprung mass to indirectly determine the direction of the sprung mass absolute velocity. A one-degree-of-freedom quarter-car model with combined tunable stiffness and damping vibration isolator based on SK and MSK control method is developed.The obtained results show that ,for only damping control, the MSK and SK methods have a good vibration control efficacy only in acceleration control under enough high damping whereas for combined tunable damping and stiffness control, the MSK and SK methods have significant vibration control efficacy both in relative displacement and acceleration. Moreover, the MSK method performs better control effect than SK under sinusoid and random excitations. Therefore MSK method is feasible in vehicle suspension system design because of its simplicity and good vibration control efficacy in both relative displacement and acceleration.
