Research Status and Development Trend of Freight Car Passing Different Gauge Railway Technology
The development status and application of passing different gauge railway technology at home and abroad are introduced.This paper expounds the key technologies of China's railway freight trains transported to countries with different gauges by replacing bogies and conversion couplers,including transportation organization mode,main structure and parameters of freight trains before and after replacement,operation conditions and line adaptability,bogie technology,coupling technology of couplers and matching of brake system,etc.At the same time,the transportation mode of interconnection and interoperability by using variable gauge bogie is expounded.The technology of variable gauge wheelset,supporting variable gauge ground device,variable gauge brake beam technology,dynamic performance simulation and variable gauge function test are studied.Finally,the development trends of two kinds of passing different gauge railway technologies,namely,the application of reloaded bogies and conversion coupler and the gauge-changeable trains with direct passing different gauge railway are proposed.
