摘　　要：文中介绍的ＳＹＳ３００型空气弹簧为自由膜式空气弹簧,其主要部件是橡胶囊,它一般由内橡胶层、帘布层和外橡胶层以及成型钢丝圈硫化而成,密封方式采用压力自密封。帘线布是橡胶囊的主要承载部件,帘线角是空气弹簧设计中的一个重要参数,帘线角的不同选择会导致橡胶囊充气后最大外径有较大的变化,同时也会对胶囊强度即铺层应力造成较大的影响。非线性有限元数值分析技术,可为空气弹簧的设计提供一种较为可靠的手段。SYS300 air spring introduced in the paper is one of free diaphragm air spring. Its main part is a pressureselfsealing rubber chamber, which commonly consists of the inner rubber layer, the cord fiber layer, the outer rubber lay-er and shaped steel wire rings by sulfuration. Cord fiber is the main bearing pari of rubber chamber. Cord angle is an im-portant parameter in air spring design. Altering cord angle will lead the maximum outer diameter of the rubber chamber tovary largely, and cord angle has great influence on rubber chamber intension, that is, spreading layer stress. Nonlinear fi-nite element numerical analysis method will be one of effective means in air spring design.
