Lightweight Design of High-speed Train under the Development of New Materials

Abstract

With the development of society and economy, the transportation demand of the railway market is constantly improving, as an important part of railway transportation; high-speed train can meet the transportation needs of long distance, large volume and high density. Compared with the automotive and aerospace industries, the development of lightweight materials of high-speed train is relatively rare, but its role cannot be ignored, the lightweight design of high-speed train is an integral part of the research on highspeed train technology at present, it is an important condition for realizing fast, efficient, safe and convenient transportation of high-speed train. With the continuous development of high-speed train technology, high-speed motor train requires more lightweight materials. This paper has carried out some research on the new materials used in high-speed train, in order to provide a certain references for the lightweight design of high-speed train.
