Ellipsoidal anisotropy friction simple pendulum support
The invention discloses an ellipsoidal anisotropy friction simple pendulum support which comprises an upper base plate the top surface of which is a plane and the bottom surface of the which is an ellipsoidal concave surface; a lower base plate the bottom surface of which is a plane and the top surface of which is a concave spherical curved surface; a hinge sliding block arranged between the upperbase plate and the lower base plate, wherein the top surface of the hinge sliding block is an ellipsoidal convex surface matched with the ellipsoidal concave surface, and the bottom surface of the hinge sliding block is a convex spherical curved surface matched with the concave spherical curved surface. According to the ellipsoidal anisotropy friction simple pendulum support, the lower portion ofthe hinge sliding block and a groove in the upper portion of the lower base plate are spherical surfaces, and the hinge sliding block rotates in any horizontal direction through the spherical surfaces; a vertical rotating gap is formed between the hinged sliding block and a groove in the upper portion of the lower base plate, vertical rotation of the hinged sliding block is achieved when the upper base plate of the support swings horizontally, then anisotropic seismic mitigation and absorption design in the longitudinal and transverse bridge directions of a bridge is achieved, and the performance of the support is good under a rapid shearing friction test with the speed larger than or equal to 500 mm/s.
本发明公开了一种椭球面各向异性摩擦单摆支座，包括：上座板，顶面为平面，底面为椭球形凹面；下座板，底面为平面，顶面为凹球曲面；铰接滑块，设置于上座板与下座板之间，顶面为与所述椭球形凹面相匹配的椭球形凸面，底面为与所述凹球曲面相匹配的凸球曲面。本发明提供的椭球面各向异性摩擦单摆支座，铰接滑块下部与下座板上部凹槽为球面，铰接滑块通过球面实现了任意水平方向的转动；铰接滑块与下座板上部凹槽间设置竖向转动间隙，实现了支座上座板水平摆动时铰接滑块的竖向转动，进而实现了桥梁纵横桥向的各向异性减隔震设计，且支座在速度≥500mm/s的快速剪切摩擦试验下性能完好。
