The invention relates to a measuring technology of deformation quantity of a container and aims to provide a system and method for quickly measuring the axial deformation quantity of a strain strengthening container. The system comprises two tooling plates mounted on the same side of the container, wherein the two tooling plates are perpendicular to the axial direction of the container to be measured, are parallel to each other and equal in height; two pull rope displacement sensors are mounted on the first tooling plate in parallel; two steel wire ropes are parallel to the axial direction of the container to be measured and equal in height and are respectively mounted between the two pull rope displacement sensors and the second tooling plate. According to the system and the method, the fast, automatic and precise measurement of the axial deformation quantity of the strain strengthening container is realized, the production efficiency is improved, and the system has the characteristics of high precision and high efficiency; the potential safety hazards caused by needing to be close to the container during manual reading are avoided; the measuring system adopts a mechanism structure, can be repeatedly used and reduces the resources; the mounting and the operation are simple and convenient, the use cost is low, the carrying is convenient, and both manpower and material resources are reduced; the measurement of different test objects can be realized through changing the lengths of the steel wire ropes or replacing corresponding parts.

Description

technical field [0001] The invention relates to a measurement technology of container deformation, in particular to a system and method for quickly measuring the axial deformation of a strain-strengthened container. Background technique [0002] The strain strengthening technology specifically implements the strain strengthening of the container by overpressure processing the inner container of the austenitic stainless steel cryogenic container after forming, and maintaining the pressure under the strengthening pressure for a period of time, so that the container is fully deformed. [0003] At present, the axial deformation of the cylinder is often measured by using a tape measure to measure the gauge length or attaching a strain gauge, which brings inconvenience to the actual production: for the former, manual reading is required, and with the increase in the number of cylinder sections and The reduction of the measurement interval time will increase the probability of erro...

AI Technical Summary

Problems solved by technology

When the container has a large deformation, the strain gauge cannot overcome the problem of easy falling off, and the strain gauge cannot be reused, so the measurement cost is increased, so the measurement efficiency of this method is low, and it is not suitable for the actual production of strain-strengthened containers.
