Program description and interim users' guide: program LMKF : time response of a linear dynamical system by the Fourier transform method (IM-MATH-035)

The method described here is for obtaining the time history response of a railway vehicle to deviation of the track from horizontal or straight. The output from the general response program AM13 (Ref. 2) is utilised along with the Fourier transform of the track shape and the required time history...
