基于节能运营的城轨交通纵断面优化设计

城市轨道交通工程建成投入运营后，节能运营就成为运行、维护和管理的重点。因此，在设计阶段就应考虑线路纵断面设计对今后节能运营的影响。此文在以工程造价最低线路纵断面设计的基础上，论述节能运营的线路纵断面二次优化设计，把列车运行能耗作为目标函数，对纵断面内的变坡点在约束范围内进行必要的的调整，使运营能耗极小化，达到节能的目的...

Optimization Design of Urban Rail Transit Longitudinal Section Based on the Energy - Saving Operation

After putting into operation of urban rail traffic engineering, saving energy operation will be the keys of running, maintenance and management. Therefore, the longitudinal section design＇s influence on energy - saving operation in design stage should be considered. On the basis of the longitudinal section design for project cost minimum line, energy - saving operation of longitudinal line second optimization design is discussed. Viewing the train operation consumption as the objective function, the point of change slope in longitudinal section is adjusted within constraints to minimize the operation assumption and achieve the goal of energy saving.
