Title:
CENTRIFUGAL PENDULUM VIBRATION ABSORBER AND DEGREE-SETTING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2014/103660
Kind Code:
A1
Abstract:
The degree of vibration of a mass body (12) in a centrifugal pendulum vibration absorber provided with the mass body (12), which is connected to a support member so as to oscillate around a pendulum fulcrum (PF) and rotate around a center of gravity (G), is set on the basis of the degree of the vibrations which should be attenuated and are produced by an engine serving as a drive device, and in consideration of at least the rotation angle (φ) around the pendulum fulcrum (PF) of the mass body (12), and the rotation angle (θ) around the center of gravity (G) of the mass body (12). As a result, it is possible to improve vibration absorption performance by more appropriately setting the degree of vibration of a mass body in a centrifugal pendulum vibration absorber provided with a mass body connected to a support member so as to oscillate around a pendulum fulcrum and rotate around a center of gravity.
