Abstract EN
To optimize the sensor placement of the health monitoring system, the dynamic behavior of the train-bridge system subjected to vessel-collision should be studied in detail firstly.
This study thus focuses on the characteristics of a train-bridge system under vessel-bridge collision.
The process of the vessel-bridge collision is simulated numerically with a reliable finite element model (FEM).
The dynamic responses of a single car and a train crossing a cable-stayed bridge are calculated.
It is shown that the collision causes significant increase of the train’s lateral acceleration, lateral wheelset force, wheel unloading rate, and derailment coefficient.
The effect of the collision on the train’s vertical acceleration is much smaller.
In addition, parametric studies with various train’s positions, ship tonnage, and train speed are performed.
If the train is closer to the vessel-bridge collision position or the ship tonnage is larger, the train will be more dangerous.
There is a relatively high probability of running danger at a low speed, resulting from longer stay of the train on the bridge.
The train’s position, the ship tonnage, and the train speed must be considered when determining the most adverse conditions for the trains running on bridges under vessel-bridge collision.
