Lightweight design is the inevitable trend of the high-speed EMU development,and also an important technical support for realizing carbon peak and carbon neutrality in the field of rail transit.In order to explore the lightweight development level of high-speed EMU in China,this paper studies the weight of different types of high-speed EMU and the weight ratio of key subsystems,such as carbody and bogie.From the perspective of system engineering,the paper proposes the lightweight design principle of high-speed EMU,and expounds the problems of structural safety,composite material operation and adaptability faced by the lightweight design of high-speed EMU.The paper introduces the application of lightweight materials such as high performance aluminum alloy and carbon fiber composites,analyzes the structural lightweight optimization technology of carbody and bogie,and discusses the lightweight method of traction system and braking system,so as to promote the development of lightweight technology of high-speed EMU in China,and provide theoretical basis and technical support for construction of the lightweight design and evaluation system of high-speed EMU in China.
