Abstract

The invention relates to a three-dimensional deformation measuring device for a measured piece in a high-temperature and low-temperature box. The measuring device comprises a string, a three-dimensional air floating assembly and signal acquisition modules with encoders in three directions. Each air floating unit comprises an air floating shaft and an air floating sleeve. The signal acquisition modules with the encoders in the three directions are respectively installed on an x-direction air floating unit, a y-direction air floating unit and a z-direction air floating unit. An x-direction air floating shaft is installed on a fixed plate. An x-direction air floating sleeve is slideably installed on the x-direction air floating shaft. The x-direction air floating sleeve is fixedly connected with a y-direction air floating shaft. A y-direction air floating sleeve is slideably installed on the y-direction air floating shaft. The y-direction air floating sleeve is fixedly connected with a z-direction air floating sleeve. A z-direction air floating shaft is slideably installed on the z-direction air floating sleeve. The upper end of the string is connected with the measured piece and the lower end of the string is connected with the z-direction air floating shaft of the three-dimensional air floating assembly. The three-dimensional deformation measuring device for the measured piece in the high-temperature and low-temperature box provided by the invention has the advantage of high measurement precision.

Description

technical field [0001] The invention relates to a three-dimensional micro-deformation measurement system, in particular to a three-dimensional deformation measurement device for a measured piece in a high-low temperature box. Background technique [0002] During the bending stiffness test, it is necessary to apply a force in a certain direction of the tested piece. Under the action of force or torque, the tested piece is deformed, and the stiffness is calculated by measuring the deformation in the direction of the force. However, the shape of the measured piece is irregular, and under the action of external force, in addition to the deformation in the direction used for stiffness calculation, it may also produce rotation in the three directions of x, y, and z and deformation in the other two directions. Even if the force or moment does not change, the moment arm will change due to the deformation of the measured point, which will affect the loaded moment value. Since the de...
