New nonlinear and thermo-dynamical air spring model for rail vehicle dynamics and passengers ride comfort improvement

The secondary suspension of most new EMU and DMU rail vehicles is equipped with air springs to serve a good ride comfort to the passengers as the performance of suspension component especially for air spring have significant effects on rail - vehicle dynamics and ride comfort of passengers a complete nonlinear thermo-dynamical air spring model which is a combination of two different models is introduced.
