Abstract


Line wheel -rail wear problems directly affecting the workload of maintenance and repair of the line in the future . For high-speed railway , the speed increase as the wheel -rail contact interaction increasingly fierce , wheel -rail wear problem has become even more obvious, how to reduce wheel and rail wear , high-speed railway will be non-ballasted track maintenance and repair of major work . Therefore, how the perspective lines from kinetic wheel -rail wear analysis of influencing factors in order to take appropriate measures to reduce the amount of wear and wheel-rail maintenance and repair capacity has important theoretical value and engineering significance . Thesis completed the following tasks: ( 1 ) Based on ADAMS / Rail software to build a complete car - line system space vibration analysis model, and the model was validated . ( 2 ) the use of the established model to analyze the high-speed railway lines cross and vertical wheel -rail wear design parameters on the impact of the law , from the perspective of reducing the wheel -rail wear and further high-speed railway lines obtained reasonable value of design parameters . ( 3 ) in contrast to our TB / T 449-2003 standard specifies the type of surface and the wear of the five European standard S1002 rim tread shape geometry , based on the analysis of a variety of high-speed railway wheel-rail matching wheel and rail wear were investigated . ( 4 ) for high-speed trains of different transport modes CDB levels, the possibility of trains at different speeds , focusing on analysis and comparison of the line and cross- line train wheel -rail wear affect the results , a clear wheel -rail wear of high-speed railway trains op mode track maintenance has highlighted the issue . In this thesis, the main innovations are: explores the high-speed railway lines and trains cross and vertical design parameters of transport modes other factors on the high-speed railway wheel and rail wear were studied , for the design and maintenance of high-speed railway to provide some useful reference.
