Program description for ADKRENTA, ADKRENTB. Programs designed to compute the time history of the response of a railway dynamical system during entry and exit from a smooth curve (IM-MATH-052)

These programs are modifications to the fast fourier transform programs developed previously (ref. 3). They are designed to permit independent inputs from the track and compound them to give total vehicle response. ADKRENTA evaluates the responses for each co-ordinate specified, while ADKRENTB considers the slip conditions for the wheelsets until...
