摘要
Air spring gas is generally regarded as an ideal gas in analysis , but this is not consistent with the actual work . Considerring influence of non-ideal gas to air spring stiffness ,and based on van der Waals equation which is closed to the real gas equation, stiffness characteristics model of air spring and air spring with auxiliary chamber are re-derived and established. Influence of non ideal gas correction factor H to air spring stiffness is analysed within the range of pressure 0.2MPa to 5 MPa and working temperature -50 °C to 50°C,and results show that , there are big errors in air spring stiffness model in the conditon of low temperature and high pressure based on ideal gas equation, and range of application of the stiffness model is expanded when H is introduced and amended.
