Shock and Vibration, Volume 2025, Issue 1, 2025.This study contributes to the dynamic amplification effects of different speeds of trains on the behavior of the ballasted railway. The damage mechanisms of the main components of ballasted railway tracks were investigated in 3D numerical modeling using the PLAXIS code. Several moving speeds have been tested.

Research on Strength Test Technology of Bogie Frames
IOP Conference Series: Earth and Environmental Science, 2020 Abstract The bogie frames play a vital role in the reliable operation of rolling stocks. In order to more effectively test the performance of the bogie frames’ strength, a test plan of bogie frames’ static tests and fatigue tests is designed according to related standards which is carried out by calculating the load and applying the load

Impact of Frog Height Deviations on Dynamic Response of High‐Speed Metro Trains Negotiating Turnouts
Shock and Vibration, Volume 2025, Issue 1, 2025.Composite frogs inevitably have manufacturing or installation errors, leading to deviations in the height of the frogs, which affects the dynamic performance of trains passing through turnouts. This study focuses on high‐speed metro systems operating at 100 km/h or higher. Based on field‐measured No.
