摘要

A simplified nonlinear model in time domain and a linear model of hydro-pneumatic suspension in frequency domain were established and the expression of static stiffness and dynamic stiffness of hydropneumatic suspension were derived out. The expression of dynamic stiffness contains the static stiffness. Equivalent static stiffness rises with tire stiffness increasing, with the pressure of non-rod cavity of suspension cylinder increasing and with the initial position of suspension cylinder decreasing. Dynamic stiffness related to frequency increases dramatically as the frequency increases. The concept of the dynamic stiffness was proposed. The vibration characteristics of hydro-pneumatic suspension in the view of frequency domain can be analyzed and it is the reference to analyze the stiffness characteristics for suspension.
