X-type anisotropism friction double-pendulum vibration reduction and isolation support
The invention discloses an X-type anisotropism friction double-pendulum vibration reduction and isolation support which comprises an upper seat board, a lower seat board, an upper hinged sliding block, a lower hinged sliding block, an upper wear-resisting board, a lower wear-resisting board, a spherical surface wear-resisting board, a dust cover, a bolt and the like. The upper seat board and the lower seat board are in an X type. The outer sides are planes, the inner sides are concave hook faces, and the concave hook faces, long edge stop blocks and short edge stop blocks form grooves. Sphere center sliding blocks are arranged inside the grooves and are formed by hinging and combining the upper hinged sliding block and the lower hinged sliding block through the spherical hook faces. Due to the fact that the curvature radius, length, friction coefficients and the like of the groove of the upper seat board and the groove of the lower seat board are set differently, vibration reduction and isolation rigidity, displacement, damping and the like in different directions are different, and the performance-based anisotropism vibration reduction and isolation design of bridges can be achieved through horizontal rotation and vertical rotation of the sphere center sliding blocks. The support has the advantages that the anisotropism vibration reduction and isolation design of the bridges can be achieved, the vibration reduction and isolation mechanism is clear, and the support is applicable to straight, oblique crossing and other bridges and is more economical.
