Measurement of Vibration of Bobbin

概要

To analyze the vibration characteristics of bobbins, it is very important to know the mode and the cause of bobbin vibrations.<BR>In this article a method to measure the vibration characteristics of rotating bobbins correctly is suggested and some results obtained there by are discussed.<BR>Vibration characteristics are affected much by these conditions : the force with which to insert the bobbin into the spindle, and the relative position of the bobbin to the spindle. Therefore, the conditions must be kept unchanged during measurement.<BR>The vibration characteristics must be measured not only at a special point (e. g, at bobbin head) but also at several other points.<BR>Plastic bobbins are deformed considerably by high-speed revolutions, about 15, 000 r.p.m., and their vibration characteristics are very different from those of wooden bobbins.
