“…By implementing a proportional integral derivative (PID) controller, they illustrated damping force controllability of the ER mount. Shawkatul Islam and Ahmed [12] compared the vibration and shock isolation performances of ER and MR dampers with linear passive damper and two-stage asymmetric nonlinear damper. They demonstrated that superior vibration and shock isolation performance of ER and MR dampers for sprung mass compared to linear passive and asymmetric nonlinear dampers.…”

In this research, semi-active control of sandwich plates with electro-rheological (ER) core and carbon nanotubes-reinforced composite facesheets using smart ER dampers is studied. Sandwich plate is subjected to the external electric field and rested on orthotropic visco-Pasternak foundation. The material properties of ER core and nanocomposite facesheets are obtained by Yalcintas model and Eshelby-Mori-Tanaka approach, respectively. The governing equations of motion are solved by a combination between finite element and Newmark methods for clamped and simply supported boundary condition. The effects of various parameters such as applied voltage, controlled electric field and initial gap of the electrodes on the vibration suppression time are discussed. The results show that the settling time of system introduced in this work is much less than previous researches in this field which is a very important advantage.

“…In order to make this happen, all the suspension components, both front and rear, must be in good working condition. To explore the suspension system, simulation models have been proposed in previous literature mostly with two degrees of freedom [1,2]; in previous work only the pitch and bounce motion of the vehicle body was considered [2]. Although the effects of various damping coefficient were analyzed, however the tire was not considered as a separate entity in most research.…”

Vibration of the suspension system of a vehicle is crucial for comfort of the passenger. In this paper, a mathematical model of the suspension system is presented with half car model with four degrees of freedom. Vibration characteristics due to different pitch line excitation and different damping coefficients are investigated for heavy vehicle suspension system. The model is simulated in MATLAB SIMULINK for this investigation. ANSYS Structural software has also been used to determine the resonance frequency and mode shape of vehicle bounce and pitch motion.
