High-speed railway ballastless track structure performance prediction method and control system

Abstract

The invention relates to a high-speed railway ballastless track structure performance prediction method and control system, and the system comprises a data collection module which is used for obtaining the data of the geometric dimension information, the distribution information and the disease type of a monitored object; the disease extension evolution model is used for predicting evolution information of the detected disease in the time dimension along with the external environment factors and the train load effect; according to the ballastless track structure performance prediction model, the change condition of each performance index of the track structure is completed through the input information of the disease evolution model, and the evolution rule of the comprehensive performance index of the ballastless track structure is obtained; the maintenance model is decided, the ballastless track structure maintenance opportunity and the range distribution of the disease maintenance combination are obtained through the established optimization objective function and an optimization algorithm, a decision maker selects a target solution to carry out corresponding maintenance operation and feeds back to the information module, disease and structure performance prediction is formed, and closed-loop operation is controlled.

Description

technical field [0001] The invention relates to a performance prediction method and a control system for a ballastless track structure of a high-speed railway. Background technique [0002] With the increase of the service time of the ballastless track structure of the high-speed railway, the small defects of the structure layer and the structure layer gradually expand under the action of the train load and the external environmental cyclic load and eventually develop into a larger local disease, which affects the durability of the ballastless track in service. , and pose a threat to the safe operation of high-speed railway trains with very strict requirements. Based on this situation, it is an urgent need for the current high-speed railway ballastless track maintenance work to improve and condense a scientific research and judgment method for predicting the structural performance of ballastless track, and then formulate precise maintenance strategies to form a complete main...
