Various vibration control devices have come into use recently in many machines and structures. This paper introduces a fundamental study of the application of a dynamic absorber for shock-applied rolls and shows its vibration-reducing performance and some other features. Shock forces applied to paper or iron sheet processing rolls cause some troubles due to bending vibrations. The above-mentioned vibration absorber has the following features. It reduces the first transient peak of displacement immediately after shock application, and its frequency is comparatively high, about 200Hz. By means of numerical simulations and fundamental experiments, the above-mentioned performance is confirmed and some information for practical use is obtained. The results are introduced in this paper as a 1st step toward practical utilization.
