AI Technical Summary

Problems solved by technology

When measuring the displacement in the horizontal direction, since the horizontal displacement occurs at the end of the column, there will also be a certain rotation angle in the vertical direction, and the contact point between the displacement meter and the column will also change accordingly. There is a large error in the measured displacement

Abstract

The invention discloses a device and method for accurately measuring displacement and belongs to the field of test measurement devices. The device comprises a plain steel plate, a bearing, a T-shaped steel plate and a displacement meter, wherein the plain steel plate is fixed on a to-be-measured component, the bearing is positioned at the center of the plain steel plate, the T-shaped steel plate is close to the position of the middle of one side of the plain steel plate and is provided with a protrusion installed in the bearing, the displacement meter is fixed at one end of a support, and the displacement meter and a to-be-measured point are on the same horizontal plane. A pointer of the displacement meter is pressed on the displacement meter, and the other end of the support is fixed on the ground. According to the device and method for accurately measuring the displacement, displacement measurement errors caused by rotation of the to-be-measured component are avoided.

Description

technical field [0001] The invention relates to a device for accurately measuring displacement, which belongs to the field of test and measurement devices. Background technique [0002] During the test, the displacement of the structure or component under load is a main test content, and these displacements are usually relatively small, generally not exceeding the millimeter level. Existing high-precision displacement gauges include dial gauges, LVDTs, etc., which can fully meet the requirements, but due to improper supporting devices or test methods, large measurement errors will result. [0003] For example, in order to study the seismic performance of buildings, the load-displacement relationship of columns in the horizontal direction usually needs to be measured. When measuring the displacement in the horizontal direction, since the horizontal displacement occurs at the end of the column, there will also be a certain rotation angle in the vertical direction, and the con...
