Dynamic Stability and Stress Analysis of Alternative Guideways for Levitation Vehicles.

摘要

Responses are predicted for several kinds of guideways subjected to the constant,transit pressures of levitation-type vehicles. The studies include:Stresses in subterranean tunnel liners with alternative vehicle support structures;comparative dynamic efficiencies of simple and two-span elevated guideways with several distributions of transit loads;dynamics of multiple,flexible post and rigid panel guidance walls;dynamics of segmented (open-jointed) guidance plates and of continuous plate strips with arbitrary foundation restraints;responses to transit moments of plate-type levitation surfaces on elastic foundations;and applications of these dynamic theories in determining stresses for alternative at-grade guideways of current importance.
