Development of rolling pendulum type dynamic absorber using magnetic damping
Nihon Kikai Gakkai ronbunshu, 2018 Purpose of this paper is to reduce the response of rocking vibration mode of vertically isolated equipment. The rocking vibration is the motion that the top of equipment vibrates as the fulcrum in a bottom end.

Development of retention plate which holds spent fuel cask
Nihon Kikai Gakkai ronbunshu, 2021 A method to retain a cask by a retention plate has been developed. In this method, a small fitting gap between the bottom of the cask and the circular hollow of the retention plate controls movement of the cask in the range of the circular hollow area at

Monitoring of train-induced vibrations on rock slopes [PDF]
International Journal of Distributed Sensor Networks, 2017 Train-induced vibrations will undoubtedly influence the stability of slopes near railway lines. To monitor the effects of such vibrations on slope stability, a wirelessly networked vibration test system was established, which included wirelessly networked vibration meters, high-precision and high-speed three-dimensional sensors and a remote wirelessly

Seismic Response Analysis of Prestressed Concrete Rocking Frame
Applied Sciences, 2021 In order to investigate the seismic performance of prestressed concrete rocking frame (PCRF), a theoretical model based on rigid body is established for a one-story single-span PCRF. The PCRF studied in this paper has the connecting interfaces set at the

Vibration Characteristics of Rock Drills
Journal of Low Frequency Noise, Vibration and Active Control, 1985 This report presents the results of field tests conducted to ascertain the vibration characteristics of rock drills from the viewpoint of hand transmitted vibration. Measurements were conducted on a number of jack leg and stoper drills while the drills were being used in a production environment. R.M.S.

Frequency Analysis of Hard Disk Drive Spindle System Supported by Hydrodynamic Bearings
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2007 Herringbone-grooved hydrodynamic bearings are now being applied to hard disk drive (HDD) spindle motors instead of ball bearings for demand for HDDs with larger storage capacities, faster access times, and reduced sizes.
