Vehicle Parameters Influence on Vertical Load-Carrying Natural Frequency of Railway Double-Track Steel Truss Continuous Bridge
The railway double-track continuous bridge vertical load-carrying frequency is calculated with the vehicle-bridge system mode1. When two lines with 20 same high-speed passenger vehicles are traveling on the 3×64 m through stud welding railway steel truss bridge from both ends, it is analyzed that the vehicle parameters how to influence the bridge vertical load-carrying frequency. The bridge vertical load-carrying frequency is influenced by the unsprung mass of each wheel-set of the vehicle, the suspension spring stiffness, the vehicle length and the mass of the vehicle. But it is independent of the speed of the train. It is shown that the bridge vertical load-carrying frequency is the vehicle-bridge system natural frequency, it is only depend on its natural parameters.
