Validation of Rail Vehicle Dynamics Model Using Accelerations Data Paper Field: Interaction between track and rolling stock

In this paper, the validation of complete rail vehicle model which includes a carbody, two bogies, and four axels with 70 degrees of freedom (DOFs) is investigated. In the vehicle model, nonlinear behaviors of primary and secondary suspension components are considered. The vehicle moves over straight line with simplified track model. To validate developed model, complete dynamic test of one IRICO DMU was performed in Tehran-Ghazvin route and measured axles accelerations are provided for the vehicle model as reference inputs. Results represent remarkable agreement between proposed model and experimental data
