Study on Design of Energy-saving Slope in High-speed Railway Station

The introduction of the design concept of energy saving slope into longitudinal section design of railway line plays an important part in optimizing the longitudinal section design,reducing energy consumption and saving operating expenses. According to the characteristics of high-speed railway,the paper proposes the design method and computational algorithms of energy-saving slope in high-speed railway station, offers calculation process and determines the constraint conditions of influencing parameters. Energy-saving slope design program modules are developed and the design of multi parametric energy-saving slope is fulfilled. On this basis,the paper conducts calculation and simulation analysis of station slope segment,the distance from station center to slope changing point of energy-saving slope,EMU marshaling weight,brake force coefficient and initial speed at the entry of the energy-saving slope,and determines the influencing degree of each factor on the energy-saving slope,which may provide references for the design of energy-saving slope.
