This paper analyzes the principle of the hydro - pneumatic spring, and found nonlinear mathematical model of the hydro- pneumatic spring, using the practice gas equation, orifice flow coefficient and thermodynamic equations. The heat balance simulation of the hydro - pneumatic spring based on the model is processed. The effect of the structure and state parameters on the thermal balance is analyzed. This Paper carries through a heat balance test to investigate effects of vibration excitation amplitude and frequency and temperature changes and other factor on dynamic characteristics of spring. The test results verify the mathematical model of gas spring.
