Design and Implementation of a Common Coupling Test Bench for China Standard EMU and CRH380B EMU

The debugging of EMU coupling is an important condition to ensure the safe and efficient operation of EMU trains after coupling. At present, CRH380B and CR400BF are the main models of China's high-speed railway, but the traditional coupling debugging equipment cannot meet the needs of debugging these two models at the same time. According to the actual demand of a domestic locomotive factory, a coupling test bench is designed that can complete the commissioning task of two types of vehicles. The test system is realized by software and hardware design, which can complete the signal test of the coupling electrical coupler of CR400BF and CRH380B head cars in static conditions. Through the actual test, the designed coupling debugging system can meet the requirements of the coupling debugging of two kinds of EMU, and has practical application significance.
