| Abstract: | The main content of this article is establishing the mathematical model of Hydro-pneumatic spring based on ideal status and the simplified conditions. When the piston rod does reciprocating movement in the sine excitation-x = Asin(2πft) , using gas under reciproca-ting motion of the relationship between the pressure and oil, the forces of the pistons are analyzed and the piston rod hydro-pneumatic spring force is computed. The purpose is setting the foundation which analyzes the Hydro-pneumatic spring characteristics of damping,stiffness, fre-quency,and other important characteristic. |
