Abstract:Research purposes :The computational system for the urban train operation was used for conducting the simulation to add up the energy consumptions of the different trains running on the slope. The the energy consumptions caused by the traction braking of the different types of train on the same combined slope were analyzed to find the value selection range of the optimal gradient corresponding to each track combination. Also the energy consumption caused by the traction braking of the same type of train on the each track combination was analyzed to find the optimal section combination corresponding to the different sectional lengths to direct the energy - saving design for the urban rail transit.
Research conclusions: On consideration of the influences of the sectional length,train type,operation model and limiting speed on the calculation result,we can draw the following condusions : (1) In the 1 000 m long section,the value selection range for the optimal energy - saving acceleration or deceleration slope was from - 18‰ to - 30‰. (2) In the 1 200 m long section,the value selection range for the optimal energy - saving acceleration or deceleration slope was From -12‰ to -30‰. (3) In the 1 500 m long section,the value selection range for the optimal energy - saving acceleration or deceleration slope was from - 12‰ to - 20‰. (4 ) Shortening the length of the energy - saving acceleration or deceleration slope and increasing the length of the follow – up slope, the energy consumption decreased progressively.
