Modeling and simulation of rail vehicle air spring system based on the software of AMESim

The air spring has a huge influence on the stationarity,stability and safety of vehicle system. In order to improve the accuracy of vehicle dynamics analysis and reduce error, it is necessary to improve the method of the modeling of rail vehicle air spring. This paper presents a method of establishing the air spring model by using the AMESim software. This method is convenient,accuracy and highly modularization. Also,it will make the analytical results more closer to the real value and it has a practical significance on the improvement of vehicle dynamic analysis. The method is expounded in details about using the components of AMESim to simulate the characteristic of air spring suspension, differential pressure valve and height control valve.
