The invention belongs to the technical field of suspension vibration reduction, and particularly relates to an integrated design and characteristic calculation method for a suspension system, which comprises the following steps of: firstly, extracting dynamic and static strokes, static balance positions and other requirements of the suspension vibration isolation system according to overall arrangement requirements and load distribution of each wheel position; the vertical rigidity of a nonlinear suspension static balance position is checked and calculated through a load and a static stroke, hydro-pneumatic spring characteristic matching and guide mechanism hard point coordinate design are carried out respectively, kinematics simulation analysis is carried out by taking arrangement space and suspension geometric kinematics as constraints, suspension vibration isolation system hard point design is carried out, and a suspension vibration isolation system is obtained. 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.
