摘要：
All system in real practice have Non-linear characteristics such as hardening spring, a quadratic damping force, and 'tyre lift-off' phenomenon, but for simplicity of mathematical modelling Linearity is considered. In this paper passive suspension system has been studied with considering Linearity and Non-linearity approach to the system. For the comparative study, a two Degree of Freedom (DOF) system quarter car model with introducing Non-linearity on stiffness and damping of a vehicle suspension have been developed. A MATLAB-SIMULINK model is also developed to compare suspension performance parameters such as Ride Comfort (RC) and Settling Time. The MATLAB-SIMULINK model is also validated with theoretical model using State Space Equation. The simulation result shows a considerable improvement in Non-linear over the Linear system which leads a more accurate analysis in design stage only. (C) 2017 Elsevier Ltd. All rights reserved.
