“…The HSU has two types of mechanism configuration: single-rod type and double-rod type. Some benefits of the double-rod type include weight savings, greater load levelling capability, and easy control of height [3]. In this work, the passive double-rod-type HSU is modified in order to devise the ERSS; a schematic configuration is shown in Fig.…”

“…. The radius of the piston is 0.049 m, the radii weighing from 20 to 25 ton [1][2][3]. Thus, the proposed of the inner and the outer cylinders are 0.023 m and ERSS provides a practical feasibility for the suspension system of many types of tracked vehicle.…”

“…These include shock absorbers [5][6][7][8][9][10], engine The primary function of the tracked vehicle's suspenmounts [11], squeeze-film dampers [12], clutches/ sion system is to isolate the vehicle body and its brakes [13,14], and smart structures [15]. Among contents from terrain-induced vibrations to enhance these applications, the ER damper (shock absorber) steering stability and to permit high vehicle speeds for vehicle systems has been considered to be one of [1][2][3]. In addition, the vehicle driver must have a the most attractive ER devices for practical realization.…”

In this paper, a controllable electrorheological fluid suspension system (ERSS) is proposed for a tracked vehicle. After identifying the Bingham properties of an electrorheological fluid, a double-rod-type ERSS is devised, and its damping characteristics are evaluated with respect to the intensity of the electric field. Subsequently, the governing equation of motion of a tracked vehicle featuring the ERSS is established followed by the formulation of a linearized state space model. An optimal controller integrated with Kalman filter is then designed in order to suppress unwanted vibrations of the tracked vehicle subjected to bump and random road excitations. Control performances such as vertical acceleration at the centre of gravity are evaluated in both time and frequency domains.
