Suppression and qualitative interpretation of temperature change in an air spring

This paper deals with the temperature change in the air spring attached to an anti-vibration apparatus. Because in industrial scenes, effects of the temperature of the air spring have not been considered sufficiently, its inner/outer temperature is measured. To suppress the temperature change, the metal absorbing/exhausting the inner heat is used, and the input voltage to servo valve is adjusted. By using both methods simultaneously, the reduction of the temperature change can be further improved. The performance of the methods is evaluated by experiments. Moreover, the thermal equivalent circuit corresponding to the air spring is provided in order to analyze the heat change.
