Abstract
A variable-stiffness mass tuned damper consists of a base and a mass-spring system positioned on the base, and is characterized in that: the mass-spring system comprises tuned mass, at least one coil spring, an internal clamping column and an external clamping hoop; two ends of the coil spring are respectively connected with the base and the tuned mass; the internal clamping column extends into the coil spring, one end of the internal clamping column is fixedly connected with the base, and the other end thereof is free along the axial direction; and the external clamping hoop is clamped outside the coil spring. The variable-stiffness mass tuned damper has the characteristics of simple structure and convenient regulation, can fast and conveniently regulate the self-stiffness, and is suitable for being used by bridges and other buildings.
Description
Technical field
The utility model relates to vibration damper, relates in particular to the change rigidity mass tuning vibration damper that a kind of bridge or other buildings use.
Background technique
Bridge vibration damper commonly used at present generally can not conveniently be adjusted self frequency, because the natural frequency of vibration of supported main structure often is difficult to obtain, energizing frequency also has very big uncertainty, therefore the vibration damper that can adjust frequency is easily had urgent engineering demand.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, and proposes a kind of simple in structurely, can realize the change rigidity mass tuning vibration damper of quick and convenient adjustment self rigidity.
For achieving the above object, the utility model adopts following technological scheme: become rigidity mass tuning vibration damper, become rigidity mass tuning vibration damper, form by base and the mass-spring system that is positioned on the base, it is characterized in that described mass-spring system comprises tuning quality, at least one helical spring, interior card cylinder and outside collar; Described helical spring two ends link to each other with tuning quality with base respectively; The card cylinder stretches in the helical spring in described, and an end is fixedlyed connected with base, and the other end is free vertically; Described outside collar is stuck in the helical spring outside.
In such scheme, described helical spring is preferably cylindrically coiled spring, and described interior card cylinder is preferably cylindrical body, is Spielpassung between interior card cartridge outer surface and the helical spring internal surface.
In such scheme, described outside collar is made up of two circular arc high elasticity steel plates, and the circular arc shaped portion of two steel plates is clamped the helical spring outer surface relatively, two bolton of two steel plates.
In such scheme, the described the other end of the interior card cylinder in the helical spring that stretches into is by flexible rod and corresponding supporting base or base connection.
Between above-mentioned base and tuning quality, can be provided with guide rod.
The utility model utilizes straight-line mass-spring system to realize the mass tuning damping, thereby changes its rigidity by the effective length that changes spring, realizes quick and convenient change rigidity mass tuning vibration damper of adjusting frequency.This vibration damper is installed on the main structure, adjusts this vibration damper and makes its natural frequency of vibration near excited frequency, and the vibration of main structure is significantly reduced.
The rigidity controlling device principle of this vibration damper is as follows:
The spring internal surface cooperates with a cylindrical body small amount of clearance, and this gap does not influence the spring proper motion.When needs are regulated rigidity, outside collar is stuck in appropriate location on the spring outer surface, outside collar applies radial force to spring, this moment, spring and inner cylindrical surface closely cooperated, it is stressed to make inner cylindrical surface participate in directly, and the following spring of clip does not then stress, and promptly the number of active coils of spring reduces, be directly proportional for its rigidity of cylindrically coiled spring and number of active coils, thereby reach the purpose that changes spring rate.The mode of this adjusting rigidity has overcome only at the spring outer surface or only in the easy problem that lost efficacy of internal surface restricted spring.
The utlity model has characteristics simple in structure, easy to adjust, can quick and convenient adjustment self rigidity, suitable bridge or the use of other buildings.
The utility model feature and other correlated characteristics are described in further details by embodiment below in conjunction with accompanying drawing, so that colleague technician's understanding.
