Abstract

The invention provides a damping device capable of reducing vibration in driving devices, such as engines, motors and the like, and a damping method. In the damping device, forced vibration generated by box shaped members (900) (motors, gears, engines and the like) of a vibration suppression device (100) is reduced through dynamic vibration absorbers (270), (280), (390) of six different degrees of freedom. Three dynamic vibration absorbers (270), (280), (390) are arranged out of the same straight line relative to three-dimensional faces (910), (920), (930) of box shaped members (900).

Description

technical field [0001] The present invention relates to a vibration damping device and a vibration damping method for suppressing vibration of a driving device such as an engine or an electric motor. Background technique [0002] So far, it is known that the structure that generates forced vibration by a force of a certain vibration frequency is composed of a spring and a hammer, and the vibration can be suppressed by installing a non-damping dynamic vibration absorber whose resonance frequency is consistent with the vibration frequency (refer to Patent Document 1). [0003] In addition, Patent Document 1 discloses a method of controlling resonance piping as a technique related to installation of a dynamic vibration reducer. [0004] In the method for suppressing vibration of a piping system described in Patent Document 1, the vibration control is performed by applying the mode analysis method and the design method of the dynamic vibration absorber to the piping system so a...
