Multi -direction absolute displacement measuring device based on zero rigidity vibration isolation structure

Abstract

The utility model provides a multi -direction absolute displacement measuring device based on zero rigidity vibration isolation structure, it includes frame, balancing weight, connect connection structure between balancing weight and frame, be fixed in the balancing weight on in order to measure this balancing weight on vertical, horizontal direction and first, the A second distance sensor and the electric connection that are surveyed distance between the vibrating structure host computer on first, A second distance sensor. Connection structure is including elastic connection respectively in coupling mechanism between the medial surface that corresponds of two first sides of balancing weight and frame and two coupling mechanism of elastic connection between the medial surface that corresponds of two seconds sides of balancing weight and frame respectively, and two the 1st coupling mechanism and two the 2nd coupling mechanism quadratures, each coupling mechanism include that X type structure and drawing connects in one of them articulated extension spring within a definite time that takes things to connecting the end. Under the condition of lower cost, the absolute displacement of a plurality of directions of direct measurement vibrating object. 本实用新型提供了一种基于零刚度隔振结构的多方向绝对位移测量装置，其包括框架、配重块、连接于配重块与框架之间的连接结构、固定于配重块上以测量该配重块在竖直、水平方向上与被测振动结构之间的距离的第一、第二距离传感器及电性连接于第一、第二距离传感器上的上位机。连接结构包括分别弹性连接于配重块的两个第一侧面与框架的对应的内侧面之间的第一连接机构及分别弹性连接于配重块的两个第二侧面与框架的对应的内侧面之间的第二连接机构，两个第一连接机构与两个第二连接机构正交，每一个第一连接机构包括X型结构及拉伸连接于其中一对连接末端的铰接处之间的拉伸弹簧。在较低成本的情况下，直接测量振动物体多个方向的绝对位移。
