Abstract：
As the main bearing structure of EMU(Electric Multiple Units), bogie frame was not only affected by complex alternating load, but also by environmental conditions, which requires high reliability, so the material selection requirements were strict. At present, the structure was made of weather-resistant steel plate imported from Europe and Japan with high reliability. In recent years, a breakthrough had been made in the development of weather-resistant and corrosion-resistant steel plate made in China. Tests had verified that its reliability was no less than that of steel plate imported from Europe and Japan, but it had not been applied in batch. Considering the cost and purchase cycle, domestic steel plate will be the main direction of frame application materials in the future. With the gradual improvement of vehicle lightweight design requirements, combined with continuous breakthroughs in industrial technology and new composite materials research,traditional lightweight materials and new composite materials will gradually replace the traditional steel plate and become the main application materials for the framework.
