Self-resetting composite variable friction damper and using method thereof
The invention discloses a self-resetting composite type variable friction damper and a using method thereof, the self-resetting composite type variable friction damper comprises a viscoelastic assembly, the viscoelastic assembly comprises an outer cylinder and an inner cylinder arranged in the outer cylinder, and a viscoelastic cylinder is arranged between the outer cylinder and the inner cylinder; the variable friction assembly comprises a variable-diameter rubber spring located in the inner cylinder and a conical friction cylinder located in the variable-diameter rubber spring, and a cylindrical piston is arranged in the conical friction cylinder; the connecting assembly comprises a fixed end lug ring connected with one side of the outer cylinder, an outer cylinder end cover connected with the other side of the outer cylinder and a movable end lug ring connected with the cylindrical piston. Through mutual cooperation of the viscoelastic cylinder, the conical friction cylinder and the variable-diameter rubber spring, corresponding damping performance can be provided for different levels of earthquakes, the energy consumption requirements of small earthquakes, medium earthquakes and large earthquakes can be better met, the self-resetting function of the friction damper can be achieved more easily, and the functionality and integrity of a building structure can be guaranteed.
本发明公开了一种自复位复合型变摩擦阻尼器及其使用方法，包括：黏弹组件，黏弹组件包括外圆筒和设置在外圆筒内部的内圆筒，外圆筒与内圆筒之间设置有黏弹性筒；变摩擦组件，变摩擦组件包括位于内圆筒内部的变径橡胶弹簧、位于变径橡胶弹簧内部的锥形摩擦筒，锥形摩擦筒的内部设置有圆柱活塞；连接组件，包括与外圆筒一侧连接的固定端耳环、与外圆筒另一侧连接的外圆筒端盖以及与圆柱活塞连接的移动端耳环。本发明通过黏弹性筒、锥形摩擦筒以及变径橡胶弹簧之间的相互配合，能够实现不同等级地震提供相应的阻尼性能，可以更好地满足小震、中震和大震的耗能需求，更易于实现摩擦阻尼器的自复位功能，可保证建筑结构的功能性和完整性。
