A method for optimizing the speed curve of high-speed trains

Abstract

This invention relates to the field of train operation optimization technology and discloses a method for optimizing the speed curve of high-speed trains. The method includes acquiring train data, route data, and operational data; dividing the train journey into multiple sub-stages and establishing corresponding time constraints based on the speed characteristics of mixed-run trains in each sub-stage; establishing a train speed curve optimization model with the dual optimization objectives of minimizing train energy consumption and maximizing train operational stability; and solving the train speed curve optimization model to obtain the optimized train speed curve result. This invention not only ensures the safety, comfort, and punctuality of train operation but also significantly improves the overall operational efficiency of train groups at different speed levels on core long-distance routes.
