- W1506973318 abstract "It is very difficult to obtain a long period vibrometer of small size because of a large influ-ence of solid friction existing in it. When the place of it where the solid friction may exist is made to vibrate with a high frequency, the influence of the solid friction may be expected to vanish to make comparatively easy to obtain a long period vibrometer of small size.In the 1st report of our study, we have already explained the behaviour of solid friction existing between a gravity pendulum and its support for the case of its free vibration when the support is vibrated with a velocity amplitude far larger than that of the pendulum. The present paper treated the case of the forced vibration of the pendulum under the action of an exterior force of harmonic time variation type and moreover under the same conditions as in its free vibration, and obtained the analytical results such that the vibrating solid friction becomes equivalent to a fluid friction and moreover the damping constant h and the damping decrement ε' of the vibration system due to the vibrating solid friction are expressed by the following forms : h=xfω02/πAωΩ, and ε'= xfω02/πAω, where xf : the solid friction displacement, ω0 : the natural circular frequency of the pendulum, A : the amplitude of the vibrating support, ω : the circular frequency of the vibrating support, and Ω2= ω02-2.Of course, due to the vibrating solid friction, in the forced displacement vibration of the pendulum is raised a vibration with the frequency ω and moreover with the amplitude of (π2/8) (ω0/ω) 2xf, but this amplitude becomes negligibly small compared with the motion of frequency ω0 to obtain a smooth motion of the pendulum.Furthermore, for the case when Aω becomes not far larger than x, the resistance characteristics of the friction become to be nonlinear about x, and the frequency response of this nonlinear vibration system has the charaRcters shown as follows : For non-resonance state, the vibrating solid friction behaves like a fluid friction, and for the state of near resonance it behaves wholly like a fluid friction when the vibration amplitude of this system is small. When the vibration amplitude becomes large, however, the vibrating solid friction behaves with its natural character." @default.
