What is Multiaxial Fatigue of High-Speed Train Bolts about?
This study analyzes the multiaxial fatigue of connecting bolts in high-speed train axle boxes under subharmonic resonance conditions. It demonstrates that common prevention methods for bolt failure are ineffective and introduces a novel dynamic stress simulation method, validated through experimental and numerical comparisons. The findings indicate that bolts are susceptible to multiaxial fatigue failure after prolonged exposure to resonance, emphasizing the need for improved maintenance strategies to enhan
