AUTOMATED GUIDEWAY TRANSIT SYSTEMS VEHICLE-ELEVATED GUIDEWAY DYNAMICS: MULTIPLE-VEHICLE SINGLE SPAN SYSTEMS

Analysis and design techniques are described for synchronously controlled AGT vehicles crossing elevated span structures. Computer simulation programs have been developed to determine time histories of guideway deflections, moments and stresses and vehicle accelerations (peak, total rms and rms in one-third octave bands) for a string of multiple AGT vehicles crossing flexible spans with random vertical, angular, camber and surface roughness irregularities. Specific data has been developed to identify operating conditions corresponding to potential span resonant conditions. A computer-aided design program has also been developed to determine span structural requirements needed to meet stress and passenger comfort conditions. Span designs for both large and small headway operation of 4, 6 and 12 passenger AGT vehicles have been determined.
