TL;DR: In this article, the authors propose a vibration damper device that includes two outer steel plates 11 installed parallel at an internal and an inner steel plate 5 installed parallel in the position middle of them, and viscoelastic members 6 are interposed in layers between the confronting surfaces of the plates 11 and 5, and sliding members 7A and 7B are fixed which can make sliding contact with the other steel plate when the plates 5, 1, 1 and/or 1 make relative displacement so that a frictional damping force is generated.

TL;DR: In this paper, the authors proposed a vibration control rubber composed of an inner cylinder, the outer cylinder 2 composed of a boss part 2A having a shaft axis P along the direction of shaft axis of the inner cylinder 1 and an outward facing flange part 2B along the radial direction of the internal cylinder 1.

TL;DR: In this article, a life estimating method of an axle spring rubber was developed to precisely estimate the life of a rubber product in its early stages without performing a durability test until rubber is broken and to develop an FEM input data processing method noticing that the time series waveform of the measured rubber is processed into the input data of finite-element analysis.

TL;DR: The active vibration-isolating device as mentioned in this paper is used for preventing vibrations due to ground motions or running of an automobile from being propagated to a platform which is disposed in, for example, a semiconductor device factory or a laser device factory, and on which various kinds of equipment are to be mounted, and also from causing the platform to vibrate.
