Abstract

The relationship of nonlinear stiffness and natural frequency of vehicle body is analyzed. Nonlinear stiffness of hydro-pneumatic spring is modeled and simulated using the software Matlab/Simulink. The impact of two main parameters to the nonlinear stiffness is analyzed. The nonlinear stiffness is added into 2-DOFs vibration model and the results of simulation are competed with linear condition. The characteristics of two levels stiffness is verified by the bench test. Finally, some conclusions as to nonlinear characteristics and impact to ride performance are given.
