扣件系统组合失效对钢轨参数的影响研究
The Effect of Combined Failure of Fastener System on Rail's Parameters
摘要
Abstract
With the Vossloh300-1 type fastener system in the field of high speed railway as the research object, the effect of combined failure of fastener system on rail's parameters of track system is analyzed. The analysis model of track system is established firstly and models for different failure conditions of fastener system are built based on the relationship between the failure of the fastener system and the three stiffness. Then, the relationships between the number of fastener failure, the rail deformation and the changing angle of the rail are analyzed under such three different combined failure conditions as the complete failure of fastener system, the complete failure of fastener spring bar and the partial failure of fastener system. The final conclusion provides a theoretical basis for the extraction of safety detection parameters of track system.关键词
