Description

technical field [0001] The invention relates to the technical field of structural component safety detection, in particular to a fast and automatic strain gauge attachment device for structural safety detection. Background technique [0002] Electrometry is a very mature method in technology, it has a history of many years, and its application scope involves various industries. The electrical measurement method is one of the commonly used testing methods in engineering structures. This method is to paste the resistance strain gauge on the surface of the component under test. When the component is deformed, the resistance value of the resistance strain gauge will change accordingly. The corresponding stress value can be obtained by changing the rate of change. [0003] In the electrical measurement method, the bonding quality of the strain gauge has a great influence on the experiment and test results. At present, the pasting of strain gauges is mostly done manually, which ...
