Abstract
With heavy multi-axle vehicle interconnected suspension system as research object, a mathematical model of elastic force of four-axis interconnected hydro-pneumatic suspension system is established and simulation and bench test are carried out. Based on the mathematical model, the stiffness characteristics of interconnected suspension and independent suspension under different working conditions are compared and analyzed, and the stiffness characteristics of interconnected suspension are also parametrically analyzed. The results show that compared with independent suspension, the stiffness of interconnected suspension system is increased and the nonlinear characteristics are obvious under single wheel excitation and rolling conditions. Each parameter has different influence on stiffness characteristics. The vertical stiffness increases with the increase of the diameter of piston rod, the increase of the initial pressure and the decrease of the initial volume of accumulator. The roll stiffness increases with the increase of the diameter of the cylinder, the decrease of the diameter of piston rod, the decrease of initial volume and the increase of initial pressure of accumulator, and the increase of installation distance of two cylinders
