The Field-Dependent Hysteresis and Fatigue Properties of Electrorheological Fluid: Experimental Results

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…

Design of a piezostack-based inertial actuator and application to vibration control: experimental investigation

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…

Integrated control on MR vehicle suspension system associated with braking and steering control

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…

Global integrated control of vehicle suspension and chassis key subsystems

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…

Damping force characteristics of electrorheological shock absorbers with different electrode designs

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…
