Suppression of train-induced resonance in high-speed railway truss bridges

Original language description

Train-induced dynamic resonance poses a significant challenge to the integrity and serviceability of high-speed railway bridges, with consequences including structural degradation, reduced passenger comfort, and a shortened operational lifespan. Although resonance and cancellation mechanisms are well established for simple beam configurations, mitigating resonance effects, particularly for higher-order vibrational modes in complex bridge systems, remains an unresolved issue. This paper proposes an integrated framework that combines wavenumber-based spectral envelope analysis, finite-element modeling, and train-bridge interaction simulations to address this problem. The spectral approach facilitates the direct identification of critical span lengths that amplify resonant response and optimal spans that promote its cancellation. Numerical results indicate that for simply-supported truss bridges, resonant excitation is effectively mitigated when the span length is 2.5 times the carriage length. In contrast, for continuous truss bridges, higher-mode resonances persist at these optimal spans, requiring the implementation of supplemental dynamic absorbers for effective control. This study offers a robust computational methodology to guide the design of high-speed railway truss bridges for enhanced dynamic performance and long-term durability.
