Abstract

The invention relates to the measurement technology of container deformation, and aims to provide a system and method for rapidly measuring the axial deformation of strain-strengthened containers. The system includes: two tooling plates are installed on the same side of the container, both of which are perpendicular to the axial direction of the container to be measured and are parallel to each other and have the same height; among them, two pull rope displacement sensors are installed in parallel on the first tooling plate; The steel wire ropes are parallel to the axial direction of the container to be measured and have the same height, and are respectively installed between the two pull rope displacement sensors and the second tooling plate. The invention realizes the rapid automatic and accurate measurement of the axial variation of the strain-strengthened container cylinder, improves the production efficiency, and has the characteristics of high precision and high efficiency; avoids the potential safety hazard caused by the need for manual reading to be close to the container; the measurement system It is a mechanical structure, which can be reused and saves resources; it is easy to install and operate, low in use cost, and easy to carry, saving manpower and material resources; changing the length of the wire rope or replacing the corresponding parts can realize the measurement of different test objects.

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.
