Damping vibration attenuation composite structure

The utility model relates to the technical field of damping equipment facilities, in particular to a damping vibration attenuation composite structure which solves the technical problem that in the prior art, a damping vibration attenuation means for equipment with the higher damping vibration attenuation requirement is lacked, and a plurality of spring arrangement grooves are evenly distributed in the lower end of a spring cover plate; bottom plate spring grooves are formed in the upper portion of the bottom plate, and a set of springs are arranged between each spring arrangement groove and the corresponding bottom plate spring groove. The mounting bolt is arranged in the center of the spring cover plate, and a first end of the mounting bolt is screwed on an upper cover; the upper cover is connected with the bottom plate through a composite sleeve structure; and the plurality of guide columns are used for limiting the radial action of the spring cover plate and the upper cover under the vibration of the spri
