Analysis and test of the heat generation and suppression of hydro-pneumatic suspension

Abstract

Hydro-pneumatic suspension is the important part of running system of vehicle, with wider working frequency band, frequent reciprocating motion and heavy impact load, whose important indicator is sealing performance. The heat generation law of hydro-pneumatic suspension is obtained under the sinusoidal excitation by calculating method, and the bench test of the temperature suppression is successfully achieved.
