Beschreibung
Zusammenfassung:The invention provides a quantitative evaluation method and system for the dynamic state of a track structure, and belongs to the technical field of railway track state detection. Time domain and frequency domain response characteristics capable of representing the dynamic state of the track structure are collected, dimensionless processing is carried out, dimensionless evaluation factors reflecting the dynamic response of the track structure are established, an evaluation index matrix is established, and the dynamic state of the track structure is evaluated. And carrying out weight assignment on the dimensionless evaluation factors in the evaluation index matrix by adopting an entropy weight method, determining entropy weights of the dimensionless evaluation factors, calculating comprehensive dimensionless evaluation indexes of the frequency domain characteristics during fusion, and comparing quantitative data results of the comprehensive dimensionless evaluation indexes to realize quantitative evaluation of
