Abstract

To study the service status and fatigue life of stitch wire, research was conducted on the stitch wire breaking in high-speed railway contact networks, and fatigue research was conducted. Based on the design parameters of the Wuhan-Guangzhou high speed railway, a dynamic simulation model of the pantograph and catenary was constructed to analyze the vibration state of the stitch wire at speed of 300km/h. Due to the lifting effect of the pantograph on the contact suspension during operation, the stitch wire mainly vibrates in the vertical direction and continuously bears alternating bending loads at the clamp position. Stitch wire were established in UG and the solid model was imported into LS-DYNA, and the refined model was subjected to stress load calculation; the stress concentration position of the stitch wire is located at the connection with clamp. Import stress history data into ANSYS nCode DesignLife to analyze the fatigue life of stitch wire under bending loads; finally, based on the Miner cumulative damage principle, the fatigue life of the stitch wire of the Wuhan-Guangzhou high speed railway at speed of 300km/h was calculated to be 4.58×106; the operating speed increases to 350km/h, and the fatigue life is 1.17×106; speed increased to 400km/h, fatigue life is 4.80×105.
