Optimal design of MR shock absorber and application to vehicle suspension
Quoc Hung Nguyen,Seung-Bok Choi +1 more
TL;DR: In this article, an optimal design of a magnetorheological (MR) shock absorber based on finite element analysis is presented, which is constrained in a specific volume and the optimization problem identifies geometric dimensions of the shock absorbers that minimize a multi-objective function.
Journal ArticleDOI
Control characteristics of a continuously variable ER damper
TL;DR: In this paper, a continuously variable electro-rheological damper for a passenger vehicle is proposed and its control characteristics are investigated, where the field-dependent yield stress of arabic gum-based ER fluid is obtained using a couette type electroviscometer.
Journal ArticleDOI
Moving switching surfaces for robust control of second-order variable structure systems
TL;DR: In this paper, the authors proposed a new switching surface which is initially designed to pass arbitrary initial conditions, and subsequently move towards a predetermined switching surface by rotating or/and shifting.
Journal ArticleDOI
Cr2O3 nanoparticle-functionalized WO3 nanorods for ethanol gas sensors
TL;DR: In this article, the reaction of the Cr2O3-functionalized WO3 nanorods sensor to 200ppm ethanol gas was 5.58, which is approximately 4.4 times higher than the pristine WO 3 nanorod sensor.
Journal ArticleDOI
Position control of a two-link flexible manipulator featuring piezoelectric actuators and sensors
Ho-Cheol Shin,Seung-Bok Choi +1 more
TL;DR: In this paper, a hybrid actuator scheme is proposed to actively control the end-point position of a two-link flexible manipulator, which consists of four actuators; two servo-motors at the hubs and two piezoceramics attached to the surfaces of the flexible links.
