VIBRATION ANALYSIS OF A RAILWAY COACH BODY USING FINITE ELEMENTS

It is now possible to automatically calculate, with satisfactory accuracy the symmetrical and antisymmetrical bending, distortional and rigid body vibration frequencies and mode shapes of a railway coach structure. The method described uses an extension of the three dimensional finite element stress analysis program NEWPAC developed by the British Railways Board Research and Development Division. Results are presented for the BR Mk III standard coach and experimental results are included for comparison.
