“…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. Kim and Ro [36] presented 7 DOF full car model by using identified equivalent parameters of kinematic structure and showed an important effect on roll related properties, whereas, Darus and Sam [38] used a linear active suspension model to check the performance of a full car model.…”

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.

“…Modeling of one and two DOF for a quarter car design a semi-active twin-tube shock has been developed by Esslaminasa et al [7]. Darus [8] adopted a state space approach in developing a mathematical model for both a quarter car and full car using MATLAB packages. In Metallidis [9], statistical system identification technique was applied for performing parametric identification and fault detection of nonlinear vehicle suspension system.…”

“…Driving comfort requires soft suspension but if for transporting cargo, hard suspension may required. Good handling requires suspension settings between this two criteria [1]. Then the suspension should be adjusted for different vehicles, for example, between the race car and limousine require different settings.…”

Abstract.The purpose of this research is to obtain a mathematical model (Full Vehicle Model) and compare the performance of passive and active suspension systems of a Three-Wheels Reverse Trike vehicle. Vehicle suspension system should able to provide good steering handling and passenger comfort. Vehicle suspension system generally only uses passive suspension components with fix spring and damper coefficients. An active suspension developed from the traditional (passive) suspension design can directly control the actuator force in the suspension system. In this paper, modeling and simulation of passive and active suspension system for a Full Vehicle Model is performed using Simulink-MATLAB software. Ziegler & Nichols tuning method is used to obtain controller parameters of Proportional Integral Derivative (PID) controller. Comparison between passive and active suspension with PID controller is conducted for disturbances input of single bump road surface profile 0.1 meters. The results are the displacement and acceleration of the vehicle body in the vertical direction of active suspension system with PID control is better in providing handling capabilities and comfort for the driver than of passive suspension system. The acceleration of 1,8G with the down time of 2.5 seconds is smaller than the acceleration of 2.5G with down time of 5.5 seconds.
