Problems solved by technology

However, there is obviously a limit to increasing the length or expanding the diameter of the linear part
For example, when the case or cover of a transmission mounted on a vehicle is used as the object to be damped, due to restrictions on mounting on the vehicle, and the problem of interference with other parts when the linear part vibrates and deforms, etc., The length and thickness of linear parts are limited, so there is a possibility that sufficient vibration damping effect cannot be obtained

Abstract

The invention provides a vibration suppressing structure which can obtain a sufficient vibration suppression effect by using a member capable of converting kinetic energy into thermal energy. A plurality of members (6) are held in contact with one another so that they can be relatively displaced. The members (6) a attached to a vibration-to-be-controlled object (1). When the vibration-to-be-controlled object (1) vibrates, the kinetic energy relatively displaces the plurality of members (6) so as to convert the kinetic energy into thermal energy, thereby suppressing vibration of the vibration-to-be-controlled object (1). A pressed contact member (9) is mounted on the members (6) so as to bring the members (6) into a pressed contact with one another and increase a frictional force between the members (6).

Description

technical field [0001] The present invention relates to a vibration-damping structure that suppresses vibration of a vibration-damping object by using a member capable of converting kinetic energy when the vibration-damping object vibrates into thermal energy. Background technique [0002] Conventionally, a technique has been proposed in which a cable or steel wire is attached to a vibration-damping object, and the vibration of the vibration-damping object is suppressed or attenuated by absorbing the kinetic energy of the vibration-damping object through the cable or steel wire. As one example thereof, JP-A-2003-328590 discloses an invention related to a vibration-damping device for a hollow tower-like structure such as a lamp post or a lightning rod. The tower-shaped structure with a vibration damping device described in this JP Unexamined Publication No. 2003-328590 is constituted in such a way that the tower-shaped structure having a hollow inside has a cable in the hollo...
