Study on Nonlinear Vibration Characteristics of Damping-Adjustable Hydro-Pneumatic Suspension
Based on the investigation on vibration characteristics of certain off-road vehicle, a new type of damping-adjustable hydro-pneumatic suspension was put forward. After the analysis of its working principle, the nonlinear dynamic mathematical models of this suspension were set up. Using the method of theoretical calculation and simulation by MATLAB/Simulink, the nonlinear vibration characteristics of this damping- adjustable hydro-pneumatic suspension were studied, including static and dynamic stiffness, dynamic output force and damping force.
