Abstract

Regarding stress distribution of railway car body, the calculation method for the strength of side frame was developed and has been used for initial design of new cars. Other parts (e.g. wheel, axle, truck framing) have been respectively designed by comparatively elementary calculation methods. However, by using finite element method (F.E.M.), these calculation methods for design can be unified and made precise. In this study, its application to structural problems of car body and stress distribution of wheel under the lateral load, centrifugal force due to high, speed rotation and temperature rise due to braking are described.
