Abstract: The importance of elevated guideway/vehicle dynamics to the design of advanced ground transportation systems is discussed and the general vehicle-suspension-guideway interaction problem is outlined. ...

Abstract: A novel pneumatic acceleration sensor utilizing a single gas-bearing supported element is described. System damping and pneumatic signal output are obtained by reverse-flow flapper-nozzle valves ...

Abstract: A rational procedure is developed for the design of a class of vortex amplifiers which operate in the incompressible flow regime. The procedure is based upon analytical and experimental studies ...

Abstract: Experimental data are presented for the threshold of whirl instability for a short, rigid rotor supported in externally pressurized compensated gas journal bearings. The effects of supply pressures ...

Abstract: A novel approach to gas servo design is presented which provides closed-center operation while eliminating close clearance sliding seals and elastic members. Pulse-length modulated pressure waves ...

Abstract: An analytical model for the static and dynamic behavior of plenum-type air cushion suspensions, including compressor and feeding duct interactions, is developed and experimentally verified. Conditions ...

Abstract: A nonlinear analytical model for the dominant low-frequency dynamic behavior of flexible-skirt air cushion suspensions is developed using bond graph notation. The model includes nonlinear fluid ...

Abstract: Static and dynamic analytical models are derived for an attractive ferromagnetic vehicle suspension. The suspension consists of a pair of laterally offset electromagnets, reacting with an inverted ...

Abstract: The fluid squeeze-film produced by relative axial or tilting motion of two closely spaced plates provides viscous damping action over certain ranges of operation. When gas is the working fluid, ...

Abstract: A primitive vehicle suspension system coupling a simple vehicle model to a guideway having random irregularities is defined. The optimum linear suspension which minimizes a linear combination of ...
