“…Results corresponding to linear, piecewise linear and experimental damping characteristics were also generated in Adams view environment for comparison purpose and to establish the validity of the model. It needs to be mentioned here that to assess the dynamic behaviour of suspension system, sprung mass acceleration (body acceleration) and body displacement are the parameters mostly used as criteria which are related with passenger comfort [8][9]27]. The quarter car and full car modelling simulations were done in the past by various researchers [2,32,38,40,42] to consider a linear viscous damping model for the shock absorber.…”

“…The simulation is carried out to plot vehicle performance for body acceleration, body displacement, suspension deflection and unsprung mass acceleration. The Adams view, a multi body dynamic analysis software, provides realistic simulation of complicated dynamic systems and hence is a convenient tool for model validation [26][27]36]. In the present paper, quarter car system with linear, piecewise linear and experimental hysteresis damping characteristics of the shock absorber is modelled using Adams view environment and subsequently appropriate results are generated to compare them with the results of Simulink analysis.…”

“…Improvement over the ride and handling characteristics of suspension system has a wide scope. Therefore, researchers use the application of software tools like Simulink and Adams view for analysis, and simulation of vehicle suspension system [24][25][26][27][28][29][30]. Adams view with quarter car model has been used to represent McPherson suspension system [2].…”

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.
