摘　　要：简介空气弹簧的主要构成,利用MSC.M arc有限元软件,建立其有限元分析模型,分析橡胶囊体帘线参数和初始内压等关键参数对其垂向特性的影响,得到不同条件下的垂向位移-载荷曲线。分析结果表明:帘线角、帘线层数和空气弹簧内部压力对其垂向特性影响较大。The major components of air springs were outlined. MSC. Marc was used to set up its finite element model. The influences of key parameters, such as the cord parameters of rubber and the initial internal pressure, on vertical stiffness characteristic were analyzed and different displacement-load curves under different conditions were obtained. The analysis results show that the parameters such as the cord angle, the cord ply number and the initial internal pressure, have evident effect on vertical stiffness characteristic of air springs.
