According to the structural characteristics of the fixed-cylinder hydro-pneumatic suspension, the force transmission and the construction of the theoretical model were discussed. The non-linear correspondence of the force between the piston and the road wheel was clarified through analytical deduction, and the formula for calculating the stiffness of the suspension was given. The influence factors of suspension leverage ratio and elastic force were simulated and analysed by programming, the conclusions drawn provided ideas for the design of zero stiffness suspension near the equilibrium position.
