The saving energy with train operation is more important than before from the view points of the global environment. However the energy saving design on the traction equipments sometimes has a trade off relation against the down sized and lighter weight traction equipments. In this paper, an optimizing method of the generic algorithm is applied to the numerical simulation to calculate the consuming...
This paper examines the fault diagnosis (including detection and localization) of a Flux Switching permanent magnet Motor (FSM). Electrical and mechanical models of fault due to a partial short-circuit on one phase is described and used on a numerical simulation in order to detect and localize the fault. Fault detection is realized by a diagnostic observer (Kalman filter) which generates residual...
The isolation effect of the non-eccentric or eccentric single building with base isolation and the multiple building with common isolation are analyzed by self developed software. The results show that, the isolation effect of using the method of non-eccentric multiple building with common isolation under seismic force is the same with the single building with base isolation. However, using the method...
Magnetic thin films of FexN were prepared by so-called "ion reacting deposition." To clarify the effect of ion beam irradiation during deposition, the difference between use of N2 ions and Ar ions was studied. A low-energy broad-beam ion source (Kaufman type) was directed normal to the substrate, which was set obliquely to the direction of iron vapor incidence. All of the FexN films consisted...
