Research on structure and dynamics calculation of the trailer bogie of the CRH2 high-speed train

Abstract

Train structure and dynamics calculations have long been of research interest. Especially, the North-South high-speed railway project is being researched for implementation. The article studies the typical trailer bogie structure of the CRH2 high-speed train. Thereby, it has conducted research on the dynamic model of the trailer, calculated the dynamics, and evaluated the operational stability criteria of the trailer. The results are not only reference documents but also have practical significance for the North-South high-speed railway project.
