The theoretical model, parameters design and experiments of domestic high working pressure and heavy duty air spring developed for the first time are studied systematically in this paper. The accurate calculation methods of high-pressure air spring’s pressure-resistant ability, stiffness and natural frequency are established. The influences of structural and technical parameters on the performance of this type air spring are analyzed and the control measures are presented. The validity of theoretical methods and effectiveness of control measures are verified by air spring prototypes and experiments. The performance of the series of air springs developed by the methods presented in this paper meets all requirements of naval vessels. The air springs have been used in the high performance mounting systems which carry tens tons of and hundreds tons of power plants.
