Summary
This paper presents new experience with the application of new materials in the
design of rail vehicle components. It also describes examples of laboratory
verification focused on the static, dynamic and fatigue properties of these
components. The research and development were realized in co-operation with the
research institutes, universities and industrial companies on a national and
international level and with the support of national grant agencies. This paper is
focused on the development of the metro hybrid bodywork where the steel with high
yield strength and sandwich composites were applied to the construction of the
sidewalls and the roof. The investigation of a smaller model of a functional sample
and finite element calculations were performed prior to the strength testing of the
real bodywork structure.
