Abstract

The invention provides a combined damper made by foamed aluminum combined material having compressibility. The damper comprises an upper connecting rod (1), an upper cover plate (2), a first middle clamping plate (41), a second middle clamping plate (42), a third middle clamping plate (43), multiple foamed aluminum combined material (6), a lower connecting rod (5), a first screw rod (31), and a second screw rod (32). The upper connecting rod (1) comprises a first rod (11) and a second rod (12) vertical to the first rod. The upper cover plate (2), the first middle clamping plate (41), the second rod (12) and the lower connecting rod (5) are sequentially arranged at intervals from the top to the bottom and opposite to each other. The upper cover plate (2), the first middle clamping plate (41), the second rod (12) and the lower connecting rod (5) are parallel to each other. The combined damper made by foamed aluminum combined material having compressibility has following beneficial effects: large-thickness aluminum foam combined material can be prepared so that requirements for load and displacement in various vibration damping fields are satisfied.

Description

technical field [0001] The invention relates to a vibration damping device for an engineering structure, which can be used in multiple fields of vibration damping and vibration control by means of series connection and parallel combination connection according to the requirements of actual load and displacement. Background technique [0002] With the rapid acceleration of my country's industrialization process, the problems of vibration and noise have become increasingly prominent, and an effective measure for noise prevention and vibration reduction is to use vibration damping devices to suppress the spread of vibration and noise. This kind of vibration reduction device is more designed as a damper, so as to reduce the dynamic response of the engineering structure under the action of dynamic load. [0003] Aluminum foam composite material is a high damping material made by filling viscoelastic materials into the aluminum foam structure with three-dimensional open pores. Th...
