ABSTRACT
orheological damper is one of the most excellent new devices for semi-active control strategy of automobile o-rheological semi-active suspension was proposed to improve the fortableness and traveling safety of - torhological dampers will be an of semi-active vibration control in vehicle suspension system for reasons of structure,small volume,energy saving,rapid response and smooth this paper,based on Bingham model,the damping force of a MRF da- mper is all the factors that affect the damping force of an MRF damper are addition the application and research status of automobile damper were intro- duce as well as the principle of o-rheological effect and position of the mag- neto-rheological principles and models of the automobile o-rheologi- acl damper was analyzed and the future focus was discussed after summaring the simulation models,control method and testing technology of automobile o-rheologiacl damper of automobile suspensionAs a kind of controllable smart material,o-rheological fluid has gained the extensive attention.
Key words: Semi-active suspension;o-rheological effect;o-rheological damper;Simulation model;o-rheologica fluid
