Abstract

The invention relates to the technical field of civil engineering, in particular to a damper and a manufacturing method thereof. A high-damping rubber fluid viscoelastic damper comprises a steel plate layer and a fluid viscoelastic material layer, wherein the steel plate layer comprises a middle steel plate and side steel plates arranged at two sides of the middle steel plate, the fluid viscoelastic material layer is arranged between the steel plate layer and the side steel plates, and the fluid viscoelastic material layer is the high-damping rubber fluid viscoelastic material layer made of high-damping rubber fluid viscoelastic material. Due to the adoption of the technical scheme, the invention has the following advantages: the vibration energy can be absorbed effectively by the deformation of the high-damping rubber fluid viscoelastic material, a hysteresis ring is full, and the fatigue resistance is good; and compared with the traditional fluid viscoelastic damper, the energy consumption property has stronger nonlinearity, and the energy consumption property is good under the condition of extremely small displacement and extremely low speed.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a damper and a manufacturing method thereof. Background technique [0002] Existing shear viscoelastic dampers are usually a combination of constrained steel plates and viscoelastic materials arranged alternately. The steel plates and viscoelastic materials are combined into a whole after treatment. The reciprocating shear deformation consumes energy. The traditional arrangement form of the shear viscoelastic damper is: the middle layer and the upper and lower outer layers are steel plates, and the viscoelastic material layer is sandwiched between the steel plates. In the viscoelastic damper, the storage elastic modulus, loss elastic modulus and loss factor of the viscoelastic material have a great influence on the performance of the viscoelastic damper. Therefore, the research and exploration of the viscoelastic material should be carried out. Contents of the invent...
