“…The vibration control response of semi-active suspension system for pitch angle acceleration was evaluated via computer simulation. El-Kafafy et al [15] investigated the effectiveness of sliding mode control (SMC) in semi-active quarter car model. Simulation work showed the effectiveness and improvement in results of proposed controller under a road hump and random road conditions for vehicle road holding ability.…”

In this paper, semi-active quarter car system with three degrees of freedom is considered for modeling and evaluation of passenger ride comfort. Experimental results of magneto-rheological shock absorber are modeled using polynomial model. The considered algorithms in semi-active quarter car suspension system include PID controller, fuzzy logic controller, hybrid fuzzy-PID controller and hybrid fuzzy-PID controller with coupled rules. Simulation responses of the controlled semi-active and uncontrolled quarter car systems are compared under bump type of road excitation in time domain. Simulation results demonstrate that the semi-active suspension system having hybrid fuzzy-PID controller with coupled rules provide best performance in controlling the passenger seat acceleration and displacement response compared to uncontrolled and other controlled cases.

“…Blundell [29] modelled the rear suspension system by using Adams view and showed the effect of rubber bush compliance on vehicle suspension movement. By using quarter car model, several researchers have carried out investigations on vehicle performance analysis [5,[31][32][33][34] using hydraulic shock absorber or MR fluid damper [35]. The full car modelling and analysis [36][37][38][39][40][41][42][43] had been carried out by some of the researchers.…”

Shock absorber is a critical element of vehicle suspension system with nonlinear characteristics. In the present work, performance of vehicle characteristics was analysed by quarter car model to study the effect of shock absorber, on the basis of linear and nonlinear damping characteristics. In addition to linear and piecewise linear, polynomial damping characteristics were considered to address the nonlinear aspect of damping characteristics. The linear and nonlinear properties of the shock absorber were incorporated in a two degree of freedom quarter car suspension system. The modelling and simulation is carried out in Adams view environment and Matlab/Simulink. A bump road profile was used to excite the quarter car suspension models. The polynomial shock absorber model was validated using experimental data taken from established literature. Simulation was undertaken to study the dynamic performance in terms of sprung mass acceleration, body displacement, suspension deflection and unsprung mass acceleration. Experimental hysteresis characteristics data, taken from established literature, were also modelled in Adams view environment and the simulated results were used for validation purpose. The suspension system response incorporating shock absorber represented by nonlinear model, hysteresis model and piece wise linear model were provided in the result section for comparison. It was observed from quantitative comparisons that the RMS values for body acceleration and body displacement of the polynomial model matched fairly well with the results of experimental hysteresis response. It was concluded that in order to study the dynamic characteristics of the vehicle accurately, nonlinear behaviour of the damper is required to be captured properly. Therefore, the proposed polynomial shock absorber model can be a better option for vehicle dynamic analysis as compared to the complex hysteresis model.
