Mathematical Modeling of Hydropneumatic Suspension System

Mathematical modeling of any system plays an important role in research and engineering applications. Development of hydropneumatic suspension system requires a complete understanding of physical phenomenon and generating governing equations of the same. In this paper, mathematical model of a typical hydropneumatic suspension system is made and simulation of such a complex multi domain system is programmed in MATLAB Simulink software. Vibration isolation potential of hydropneumatic suspension system is investigated through mathematical modeling, incorporating nonlinearity due to polytropic nature of gas spring.
