GUIDEWAY SIDEWALL ROUGHNESS AND GUIDEWHEEL SPRING COMPRESSIONS OF THE DALLAS/FORT WORTH AIRTRANS. RESEARCH REPORT

The instrumentation of an AIRTRANS vehicle at the Dallas/Fort Worth Regional airport has been accomplished to study guideway sidewall roughness and guideway sidewall steering forces. Guidebar accelerations and guidewheel spring compressions were recorded and digitally processed to yield power spectra of guidewheel spring compressions and guideway sidewall roughness. From the spring compression data, it was learned that the forces transmitted to the guidewall through the front steering assembly of the vehicle can be at least one order of magnitude large in a sharp (150 ft. radius) curve of the guideway than in the more gentle (approximately 800 ft. radius) curves. An analytical expression for the guideway sidewall roughness was developed and it was found that AIRTRANS guideway sidewalls have more high wavelength roughness and less low wavelength roughness as compared to the vertical roughness of typical highways. The magnitude of the sidewall roughness was found to be comparable to the roughness of interstate quality highways. /Author/
