DEFINING GUIDEWAY IRREGULARITY POWER SPECTRA IN TERMS OF CONSTRUCTION TOLERANCES AND CONSTRAINTS

In order to define the correlation between guideway power spectra and corresponding construction tolerances and constraints, a digital computer program for simulating the construction of several miles of guideway has been developed. The inputs to the program include statistical accuracies associated with achieving specified profile elevations in addition to constraints on allowable maximum and minimum profile deviations. Results for guideways with lengths up to 46.5 miles are presented. Of particular interest is the leveling-off characteristic of the long wavelength portion of the spectrum due to profile relative deviation constraints. These results provide insight into how various constraints on the profile elevation can influence the long wavelength irregularity characteristics which dramatically influence the ride quality of high-speed vehicles such as tracked air cushion vehicles.
