Abstract This paper presents vibration control performances of a quarter vehicle magnetorheological (MR) suspension via new control strategy considering hysteretic behavior of MR damper. In order to achieve this goal, a commercial MR damper, Delphi Magneride™ which is applicable to high class passenger vehicle is adopted. The MR damper has 더보기…
Abstract This work experimentally presents the field-dependent hysteresis behavior and fatigue property of an electrorheological (ER) fluid. A Couette type electroviscometer is employed to measure the field-dependent hysteresis of the yield shear stress. The hysteresis is then identified by adopting Preisach model and verified through the comparison between predicted and 더보기…
Abstract This paper presents design of a frictionless magnetorheological (MR) damper which can be used for the integrated isolation mount for ultra precision exposure system. The vibration sources of the ultra precision exposure system can be classified as two. The one is environmental vibration from the floor, and the other 더보기…
Abstract This article presents a new type of a MR damper designed for an integrated isolation mount for an ultraprecision manufacturing system. The vibration sources of the ultraprecision system can be classified as two: one is environmental vibration from the floor, and the other is transient vibration occurred from the 더보기…
Abstract In this work, an inertial actuator featuring a piezoceramic stack is proposed and applied to vibration control of a flexible beam structure. After identifying the field-dependent displacement of the piezoceramic stack, an inertial actuator consisting of the stack and an inertial mass is constructed and its actuating force is 더보기…
Abstract This article presents a hierarchy control strategy for magneto-rheological suspension system integrated with active braking and active front steering subsystems. This is proposed for the improvement of ride comfort and vehicle stability under different kinds of driving conditions. A nonlinear complicated full vehicle model which includes the longitudinal, lateral 더보기…
Abstract This paper presents a new integrated control methodology for vehicle chassis subsystems associated with controlled suspension, braking system, and steering systems. In order to reflect the practical vehicle better, a non-linear complicated full-vehicle model which includes longitudinal, lateral, and vertical dynamics is established and combined with the modified non-linear 더보기…
Abstract This article presents the effect of electrode design parameters on the damping force of an electrorheological (ER) shock absorber for passenger vehicles. As a first step, an ER fluid is synthesized by dispersing arabic gum particles into non-conducting oil, and its field-dependent Bingham characteristics are experimentally evaluated. The Bingham 더보기…
