Abstract

PURPOSE:To effectually suppress the vibration of a long rod, by attaching a vibration system made of individual members of appropriate natural frequency and damping properties, to the natural frequency vibration loop part of the long rod to reduce the harmful natural frequency vibration loop amplitude of the rod. CONSTITUTION:A vibration system made of a damper C, a mass M and a spring K and having a natural frequency as a single member, which is by 20-50% lower than the harmful natural frequency of a long rod, is provided near the natural vibration loop of the rod. A spring 2 equivalent to the spring K is provided concentrically to a vertical long rod 1, for example, so that the lower end of the spring 2 is in contact with the rod 1. A weight ring 3 equivalent to the mass M is provided concentrically to the rod 1 so that an appropriate clearance is set between the ring and the rod and the ring is secured on the upper end of the spring. A sliding ring 4 is provided on the former ring 3 concentrically to the rod 1 so that an appropriate clearance and an adequate frictional force are set between the ring 4 and the rod. This results in effectually suppressing the vibration of the long rod such as a metal rod, the damping by the material of which is low.
