Theoretical and Experimental Study of Semi-Active Four-State Switchable Damper Suspension System with Dynamic Air Spring

Abstract

In this paper, 1 / 4 car test rig is used to evaluate the performance of semi-active four state switchable damper suspension gadget with dynamic air spring. a theoretical model is developed for a quarter automobile and its parameters are diagnosed. Furthermore, the paper affords a theoretical assessment of the dynamic air spring model and the techniques of semi- active four state switchable damper suspension device are suggested, and compare the outcomes received to the ones given via the semi active four state switchable damper gadget and the passive dynamic air suspension device. As a result the superior four state semi-active suspension structures provide worthwhile enhancements while as compared to the passive dynamic air suspension system. Developments within the experimental results are appropriately anticipated by way of the theoretical version.
