A corresponding nonlinear rigidity model and an adjustable vibration reduction valve system damping characteristic model are constructed in combination with a suspension thermodynamic model, structural parameters of key elements of the hydro-pneumatic spring are determined, finally, structural design of the suspension system is conducted in combination with the design scheme of the hydro-pneumatic spring and a guide mechanism, and the process of hard point coordinate, structural parameter and strength analysis is repeatedly iterated. And finally, a high-compactness nonlinear suspension system scheme is formed.
