Abstract Research purposes： With numerous railway lines laid in the yard， high - speed railway station should not only meet the operation requirements of train to pass in high speed，but also satisfy the demand of high - speed train to arrival, departure and turn - back in station yard. For the influence of speed reduction of train and station arrangement， radius of curve on arrival - departure line is much less than that of curve on main line, and parameter selection of lines connecting main line and arrival - departure line affects the travel quality of train directly. Referring to existing researches，and based on the dynamic theory and wheel - rail contact mode，dynamic analysis model was established， considering the running conditions of train between the main line and the arrival - departure line in high - speed railway station yard. Using the established model, effects on travelling safety and stability of train aroused by length variation of intermediate straight line and transition line connecting turnout on main line and curve on arrival - departure line behind turnout were calculated. Accordingly， theoretical basis is provided for the parameter optimization of lines connecting arrival - departure line and main line in high - speed railway station yard.
Research conclusions ： Based on related researches on the matching relation of superelevation and transition curve length with circular curve radius, required calculation parameters were selected, and calculations on the relation between travelling quality of train and parameter variation of connection lines between main line and arrival - departure line indicate that ： (1) To meet the demand of traveling stability, intermediate straight line with length not less than 9 m was proposed to be set to connect turnout on main line and curve on arrival - departure line in high - speed railway station yard. (2 ) The increase of transition curve length has rarely influence on easing vehicle vibration on circular curve as the length of transition curve reaches a certain value. (3) Guidance is provided to space distributionand parameter selection of lines connecting main line and arrival - departure lineinhigh - speed railway station yard, when the scale of station yard is limited.
