10912 Study on Independent Tuning of Damping Property by Cooperation of Electromagnetic Dampers for Automobiles

Abstract

皿 le electro即 etic damper， which is composed of an electric motor and a ball screw and nut ， has been proposed ． The electromagrietic dampers have high responsiveness ， cDntrollability ， and energy sav血 9 perfornlance． Besides 血ese advantages ， electromagrietic dampers can be co 皿 ected to each o 血 er very easily ． Iheref ｛ ) re ， the authors focus on this eharacteristic ofelectromagrietic damper and propose a rnethod to use the electromagrletic damper fbr the coupled suspension system ． this pape ら the authors propose a method to combine the front electromagnetic damper with thc rear through an electric ch ℃ uit． ugh vibration experiments using twe motors and electric circuits ， the perforrnances ofproposed systern are examined ， The resuhs hldicate the proposed system is ef 驚ctive and valid ．
