Abstract

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, Ahead of Print.
A multiscale finite element method is used to develop a model of a carbon fibre-reinforced plastic (CFRP) bogie with variable cross-sections and ultra-thick laminates. The model is applied to examine how CFRP influences the dynamic performance of the ...
