Abstract:Vehicle riding comfort is deteriorated not only by low-order but also by high-order resonance in the suspension system. This paper proposes to arrange the nonlinear energy sink (NES) on the tire to suppress high-order resonance. Two modal resonances can be controlled by a vibration control scheme of the distributed NESs. A dynamic model of a 2-degree-of-freedom quarter-vehicle (2-DOFQV) suspension system integrated with two NESs is established. Then, the model is analyzed approximately analytically by the harm… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
