Potential advantage of thin‐ply on the composite bolster of a bogie for a high‐speed electric multiple unit

The application of composite materials in bogies for high‐speed electric multiple units (EMUs) has been regarded as a technical breakthrough. The application of composite materials in rail vehicles began late in China. Currently, most composite materials are used in non‐load‐bearing components on the track, and applications in bogies, tie beams, and other load‐bearing components are not mature. In this paper, we innovatively apply a design...
