Program specification and users guide: Program AM 12 conversion of track spectra to input track spectra for program AM 13 (TN-MATH-2)

The theoretical study of the response of a railway vehicle to random track irregularities using Digital Computer Program AM13 (Ref 1) often requires the use of measured track spectra. The track spectra output by the programs, which process the data from the track measuring machine (TMM 1, Ref 2), are...
