摘要
为了精确测量结构断面错动微量值、解决传统测量方法存在的问题,自主设计了一套结构断面错动测试装置。该装置由弹簧片形成的小梁、固定端、应变测量系统等组成。通过改变小梁的长度和厚度控制测量装置的分辨率和工作范围;通过改变应变测量系统的桥路组合以满足测量方向的要求。该装置可以直接测量近距离两点间的错动量,可以进行单向测量和双向动态测量。该装置适用性强,测量精度为±0.002 mm,具有较强的应用价值。
In order to accurately measure the micro-displacement of structural cross-section and solve the problems existing in traditional measurement methods,a set of testing device for structural cross-section dislocation is independently designed.The device consists of trabecula,fixed end and strain measuring system formed by spring sheet.The resolution and working range of the measuring device are controlled by changing the length and thickness of the trabecula,and the bridge-road combination of the strain measuring system is changed to meet the requirements of the measuring direction.The device can directly measure the staggered momentum between two points in close range,and one-way measurement and two-way dynamic measurement can be carried out.This device has strong applicability and measurement accuracy of(±0.002 mm),and has strong application value.
