This research was conducted in cooperation with Kyudenko New Energy Co., Ltd., to measure deformation on wind turbine blades and gather actual data on wind conditions for Wind Turbine #10 of the Kushikino Reimei Wind Farm (in operation since Nov. 2012), in Kushikino, Kagoshima Prefecture. Based on the gathered measurement data, the wind direction that most impacted the structural strength of the turbine was identified, and the data was analyzed in detail. To examine into the failure analysis method based on...

Acoustic diagnosis Acoustic source localization Condition monitoring
In order to investigate a method for efficiently monitoring multiple machines in a building with an acoustic sensor, an experiment was performed to acquire acoustic data of three rotating machines running simultaneously in a state in which all three machines are normal or one of three is abnormal, with two microphones placed at different positions. The abnormality can be detected from the acoustic signal level, and it can also be specified that the bearing abnormality has occurred by frequency analysis. A m...

Electron Irradiation High Chromium Steels Phase Decomposition Positron Annihilation Spectroscopy Thermal Aging
The phase decomposition behaviour of an experimental High-chromium Ferritic steel containing 40 wt.% chromium (Fe-40Cr) irradiated with 8 MeV electrons was studied by positron annihilation lifetime (PAL) measurements and coincidence Doppler broadening (CDB) of positron annihilation radiation measurements.
Electron irradiation at 100
and at 475 ?C were performed on the specimens to nominally 0.03 to 0.3X10-3 dpa.
The rapid increase of W-parameter obtained from the specimen irradiated at 100 ?C is most like...

Aging management technical evaluation Irradiation assisted stress corrosion cracking Low cycle fatigue Neutron irradiation embrittlement Thermal aging of cast stainless steel.
Aging management technical evaluation (AMTE) is required for LWRs every 10 years at and after 30 years operation in Japan. Result of the AMTE is put into plan of a long-term maintenance program of each plant. Methods for implementation of aging management measures were set forth in “Code on Implementation and Review of Nuclear Power Plant Ageing Management Programs” of Atomic Energy Society of Japan. Technical basis of material aging evaluations in the standard are described in this paper....

acoustic emission sensor ground anchor nondestructive inspection tension
The purpose of this research is development of tension measurement method using hammering sound diagnosis technology using Acoustic Emission sensor. Experiments using actual size anchors and FEM analysis quantitatively evaluated the relationship between the vibration characteristics of the anchor head and the tension introduced into the anchor. As a result, it is possible to evaluate the anchor tension based on the natural vibration characteristics of the anchor head.
