Performance Analysis and Behaviour Characteristics of CVD (Semi Active) in Quarter Car Model

Semi-active suspension uses a special adaptive damper whose damping properties vary with road conditions under the influence of an electromagnet. the adaptive damper is used along with a sophisticated electronic circuit which constantly monitors the changing road conditions and adapts accordingly. the aim of this paper is to simulate and analyze a simple and low-cost semi active suspension system using „matlab and simulink. platform and establish its superiority, and also involves the development and simulation of a virtual quarter car model. thereafter the graphical results obtained are analyzed. the model is developed using equations of motion involving stiffness, damping ratio and displacement. these equations are translated into a simple data flow circuit in the simulation software to obtain definite results in the form of graphical output .this paper aims at the development of a simpler and cheaper semi active suspension system which will allow its fitment in comparatively affordable cars
