摘要
通过建立轴箱内置和外置的高速列车车轴承载理论模型、有限元模型和车辆系统动力学模型，研究轴箱布置方式对车轴受力状态、应力分布和动荷载的影响。结果表明，轴箱内置的高速列车车轴所承受的最大合成弯矩仅为传统轴箱外置车轴的 50%，充分挖掘了轴身的承载潜力，在实现轻量化设计方面有着独特的技术优势。与传统轴箱外置式车轴相比，轴箱内置的方式使得车轴的临界安全截面转移至轴颈两侧的过渡区域。轴箱内置式车轴轮轨垂向力的极限增减动力载荷明显低于传统轴箱外置式车轴，而轮轴横向力的极限增减动力载荷略高于传统轴箱外置式车轴，两者均有利于降低车轴所承受合成弯矩水平。综上得出轴箱内置车轴是一种在高速铁路领域极具应用潜力的新型铁路车轴结构。
Abstract
Theoretical models
finite element models and vehicle system dynamics models of both inside and outside journal high- speed train axles were established for the load-bearing capacity analysis
then the load-bearing states
stress distribution regularities and dynamic loads of these train axles were systematically studied. Result shows that the inside journal axles can achieve higher efficiency and utilization of the axle body
and the maximum combined bending moments are only half of the traditional outside journal axles
therefore
inside journal axles realize a great advantage in the lightweight design; compared with traditional outside journal axles
the critical safety positions of inside journal high-speed train axles transfer to transition positions on both sides of the journal; Compared with traditional outside journal axles
the novel inside journal axles can significantly alleviate the limit value of wheel-rail vertical force
and the limit value of wheel-axle lateral force is slightly higher
both are conductive to reducing the synthetic moments of the axles. In summary
the novel inside journal train axles is identified with a great application prospect for high-speed train vehicles.
