Abstract EN
Field tests and numerical simulations are combined in this paper.
Cross-sectional dimension measurements, dynamic performance tests, and forced vibration tests were performed on the NO·40 beam bridge of the Xin-Tai Railway.
By comparing the test results with the specifications, the current service status of the bridge was evaluated, and the basis for subsequent correction and verification models was provided.
A dynamic coupled finite element model of the passenger-freight-cable-track-bridge was established considering the degree of bridge damage (0%∼50%) and the track irregularity, and the model simulation results for the Xin-Tai Railway NO·40 bridge were measured.
The results are compared to verify the correctness of the model.
The results show that the damage to the bridge will affect the vertical displacement response and the safety stability of the train.
The vertical displacement response of the bridge midspan is twice that of the bridge performance.
When the damage level of the bridge is 30%, the passenger and freight trains exceed the safety warning limit, which should cause concern.
