Abstract

The estimation of internal pressure in trains is crucial for designing and operating vehicles safely, ensuring both passenger comfort and structural integrity. However, modeling internal pressure presents challenges due to various uncertainties. This study focuses on estimating internal pressure by evaluating different modeling approaches based on experimental measurements conducted on a full-scale train travelling on a track with tunnels presence. To determine the parameters of pressure models efficiently, a rapid and effective method is employed. Modeled internal pressures are then derived using the fitted parameters and experimental external pressures. The comparison of these models against experimental measurements identifies the most suitable internal pressure model for the specific train under consideration and for similar types of vehicles.
