Abstract：Based on a continuously adjustable inerter, a skyhook-inertance control was proposed with the effect equivalent to that of increasing sprung mass. The quarter suspension models of traditional suspension and skyhook inerter suspension were established by Matlab/Simulink, and the properties were compared. The influence of parasitic damping in inerter on the suspension performance was discussed. The results show that compared with traditional suspension under unload condition, 33.0% improvement can be achieved for the natural frequency of skyhook inerter suspension, and the root mean square of body acceleration and the dynamic tyre load of skyhook inerter suspension are improved by 52.3% and 35.5%, respectively. The skyhook inerter suspension can improve the ride comfort of vehicle with better adaptability under unload condition. The smaller the ratio of parasitic damping to inertance is, the more obvious performance improvement is. The skyhook-inertance control can solve the problem that the skyhook damping control has poor adaptability under no-load and full load conditions.
