Identification of the Combustion Engine Resistance to Motion Torque Components
Communications, 2011 Identification of the combustion engine resistance to motion is necessary in all investigations aimed at limiting frictional losses. Despite many attempts to measure the frictional resistance components, there are still no functional test beds that would

Study on seismic isolation system for long-period ground motion
Nihon Kikai Gakkai ronbunshu, 2015 In this paper, the authors have developed a new type of horizontal seismic isolation system which has large effect of vibration isolation for ordinary earthquakes and suppresses the resonance of the isolation system due to long-period ground motions ...

Journal of the Japan Society of Precision Engineering, 1968 In this paper, frictional vibrations are experimentally investigated. The experiments are compared with the theoretical analysis in the previous report. The obtained results are as follows : 1. Amplitude characteristic from experiments is agree well with the theoretical analysis which includes a time effect. 2.
