摘　　要：介绍了空气弹簧的热力学特性,对空气弹簧的垂直刚度特性和阻尼特性进行了分析。结果表明:空气弹簧的刚度不仅与其静平衡位置时的压力和容积有关,还与其有效面积变化率和体积变化率有关。空气弹簧的阻尼特性与空气弹簧本身结构有关,同时还受外界激扰频率及振幅的影响。当外界激扰条件发生变化,空气弹簧系统的阻尼特性也将随之改变。The thermodynamic characteristics of air spring are introduced. Also analyzed are the vertical stiffness and dampness characteristics. The results show that the stiffness is dependent not only on the pressure and volume at static balance, but also on the change rates of efficient area and volume. The damping characteristic is relevant with the air spring structure and is influenced by external excitation frequency and amplitude. It will change accordingly with the excitation conditions.
