A multi-dimensional scroll spring and coil spring combined tuning vibration damping device

Abstract

The invention discloses a multi-dimensional volute spring and coil spring combined tunable vibration reduction device which comprises a protection cylinder, wherein a plurality of spring boxes are arranged inside the protection cylinder; the spring boxes are fixedly arranged on a trough plate on the top of a supporting rod; and the bottom of the supporting rod is connected into the protection cylinder bottom plate by virtue of bolts. Volute springs are coiled inside the spring boxes; one ends of the volute springs are fixed on coiler shafts in the spring boxes; the other ends of the volute springs extend out of the spring boxes and penetrate through bearings to be connected onto universal spherical hinges; and the universal spherical hinges are arranged in grooves in side faces of a mass block. Spring supports are oppositely fixedly arranged on inner walls of the protection cylinder and upper and lower surfaces of the mass block, and the spring supports are arranged at two ends of vertical springs in a sleeving manner.

Description

technical field [0001] The invention relates to the field of vibration control of civil structures, in particular to a multi-dimensional vortex spring and spiral spring combined type tuning and damping device. Background technique [0002] Under the action of wind load or earthquake, the building structure is subjected to external loads to produce severe vibration, which is very harmful to the engineering structure itself. Under such reciprocating motion, structural members are prone to continuous failure, resulting in extensive collapse and damage. Structural vibration control is an effective method to solve the failure of building structures under external excitation. Vibration control methods combine human subjective initiative and natural uncertainty, which can effectively suppress the vibration response of building structures and ensure the safety and durability of structures. [0003] At present, there are many vibration reduction methods that can be used in the vibr...

Problems solved by technology

However, when the vibration amplitude of the mass block is large, the coil spring will have a large deformation, and it is difficult to achieve the ideal vibration reduction effect in the case of limited design space.
