The quality of ride is predominantly controlled by the design of the secondary suspension in rail vehicles.
That is why air springs are increasingly important suspension component in rail vehicles. This is necessary
for higher preload, higher speed as well as improved ride dynamics and noise levels. These necessities
have created an interest for modeling the air springs for the simulations of train dynamics.
In this study, some kinds of air spring models such as simple spring-damper model, Nishimura,
Vampire, Simpac and Gensys are explained. Then, the secondary suspension in the bogie of the rail
vehicles serving in Istanbul Transportation Co. in Istanbul have been modeled as a simple springdamper model and Nishimura model. Finally, the results of these two models have been presented
