Abstract: Aiming at the phenomenon of the axle box spring fracture of passenger train,applies the three dimensional software to model the parameterized axle box single coil spring,and analyzes the performance of spring caused by the gaps between the support circle and effective circle through ANSYS software.The strength,stiffness and fatigue strength of spring were calculated in Workbench system,which concluded that these performances can met the design requirements of spring.The first ten order modal vibration modes and their corresponding natural frequencies data of the axle box spring were obtained by modal analysis,and analyzed the modal vibration modes and frequency data can avoid the resonance phenomenon from axle box springs and frames.The parametric modeling method and analysis result can provide theoretical reference for designing the other axle box spring of high-speed trains.

Key words: axle box spring, parametric modeling, strength, stiffness, modal
