Friction pendulum with low starting force and variable friction coefficients
The invention discloses a friction pendulum with low starting force and variable friction coefficients, and belongs to the technical field of seismic reduction and isolation. The friction pendulum solves the problems that in the prior art, the starting sensitivity is relatively low, the friction coefficients cannot be adjusted, and the starting force is relatively large. The friction pendulum is technically characterized in that a seismic isolation unit is arranged between an upper plate and a lower plate, and comprises a lower sliding part, a conversion sliding block and an upper connecting block, the three components make contact with one another without fixing measures; the top surface of the lower sliding part is an inwards-concave arc surface, the bottom surface of the conversion sliding block is an outwards-convex arc surface, and the inwards-concave arc surface and the outwards-convex arc surface are curved surfaces with the same curvature; the top surface of the conversion sliding block is an outwards-convex arc surface, the bottom surface of the upper connecting block is an inwards-concave arc surface, and the outwards-convex arc surface and the inwards-concave arc surfaceare curved surfaces with the same curvature; and the top surface of the upper connecting block is fixedly connected with the upper plate, and the bottom surface of the lower sliding part is fixedly connected with the lower plate. The friction pendulum is particularly suitable for earthquake protection of free-standing cultural relics, precision equipment and the like with the relatively large mass.
一种低启动力变摩擦系数的摩擦摆，属于减震隔震技术领域。解决了现有技术启动灵敏度较低，摩擦系数不可调，启动力较大的问题。技术要点：隔震单元置于上板与下板之间；隔震单元包括下部滑动部、转换滑动块及上部连接块，三个构件之间相互接触，且没有固定措施；下部滑动部的顶面为内凹的圆弧面，转换滑动块的底面为外凸的圆弧面，内凹的圆弧面与外凸的圆弧面为相同曲率的曲面；转换滑动块的顶面为外凸的圆弧面，上部连接块的底面为内凹的圆弧面，外凸的圆弧面与内凹的圆弧面为相同曲率的曲面；上部连接块的顶面与上板固定连接，下部滑动部的底面与下板固定连接。本发明尤其适用于质量较大的浮放文物、精密设备等的地震保护。
