Dynamic Interaction of Elevated Guideway with Uncontrolled Maglev Vehicles [PDF]
A flexible guideway on an elevated foundation is a key to affordable maglev urban transit. The flexible guideway can undergo significant dynamic motion, either when a vehicle solely relies on an open-loop control system or when a vehicle equipped with ...

Analysis of guidance and levitation forces between HTS magnets and conductive tubes for Hyperloop
High-temperature superconducting (HTS) magnets combined with linear synchronous motors and electrodynamic suspension (EDS) are considered as one of the most suitable technologies for Hyperloop. However, HTS magnets on pods generate strong magnetic fields,

Laboratory investigation of electric charging of dust particles by electrons, ions, and UV radiation [PDF]
In many cosmic environments electric charging of dust particles occurs by electrons, ions, and UV radiation. In case of interstellar dust particles the value of their electric charge can have, for instance, very important consequences for their ...

A review of load models for the prediction of footfall-induced vibration in structures [PDF]
Crowd induced dynamic loading in large structures, such as gymnasiums or stadium, is usually modelled as a series of harmonic loads which are defined in terms of their Fourier coefficients.

ShakeNet: A portable wireless sensor network for instrumenting large civil structures [PDF]
We report our findings from a U.S. Geological Survey (USGS) National Earthquake Hazards Reduction Program-funded project to develop and test a wireless, portable, strong-motion network of up to 40 triaxial accelerometers for structural health monitoring.

Magnetic bearings-state of the art [PDF]
Magnetic bearings have existed for many years, at least in theory. Earnshaw's theorem, formulated in 1842, concerns stability of magnetic suspensions, and states that not all axes of a bearing can be stable without some means of active control. In Beam's

Ensuring Safe Exploration: Ares Launch Vehicle Integrated Vehicle Ground Vibration Testing [PDF]
Ground vibration testing has been an integral tool for developing new launch vehicles throughout the space age. Several launch vehicles have been lost due to problems that would have been detected by early vibration testing, including Ariane 5, Delta III,
