Description

Dustproof device of laminated corrugated damper Technical Field The utility model relates to the technical field of corrugated shock absorbers, in particular to a dustproof device of a laminated corrugated shock absorber. Background The laminated corrugated damper is a device for vibration control of an engineering structure, combines the characteristics of vibration reduction and corrugated structure, is composed of multiple layers of materials, comprises metal plates and damping materials, is formed by overlapping the layers of materials in a corrugated mode, increases rigidity and stability of the structure, enables the damper to adapt to different types of vibration modes, and when the engineering structure vibrates, the corrugated structure inside the damper can disperse and absorb vibration energy, generates heat in the vibration process and converts the vibration energy into heat energy, so that vibration is reduced and transmitted into the structure, and the corrugated design is helpful for controlling displacement of the damper, and keeps stability of the damper in the vibration process. When the temperature rises, the materials such as metal material and rubber that use in the bumper shock absorber can expand, can lead to the size increase of bumper shock absorber, on the contrary, when the temperature reduces, the material can shrink, probably lead to the size reduction of bumper shock absorber, can lead to rigidity and damping characteristic of bumper shock absorber to change to influence its shock attenuation effect, adopt among the prior art to use flexible connecting piece more, with the expend with heat and contract with cold of adaptation material, but flexible connecting piece can make the position of connection comparatively fragile, leads to life reduction, usability reduces.
