Simulation and comparison of quarter-car passive suspension system with Bingham and Bouc-Wen MR semi-active suspension models

Abstract

In this paper we want to transposion the suspension system in MATLAB, Simulink®, based on equation of motion. Consider only vertical movement of the car, neglecting roll and pitch. All movements of the car axes are modeled as having equal amplitude. The characteristic equations that describe the behavior of dynamical systems based on FBD (Free Body Diagram) of automotive suspension. It will make two models, one passive and one Bingham semi-active. Their responses will be compared between them, and with another Bouc-Wen semi-active model, more complex. Semi-active suspension systems have received significant attention in recent years because they offer the adaptability of active control devices without requiring large power sources. Given that both passive and semi-active dampers are in mass production will follow the normal parameters and their economic efficiency. These models are used for initial design of suspension system. © 2013 AIP Publishing LLC.
