AI Technical Summary
In existing methods for stress-strain testing of metal hydride hydrogen storage tanks, prolonged immersion of strain gauges in water leads to a decrease in the adhesive bonding strength, affecting the continuity of testing and the integrity of data.
The structure combines a sealing ring with a waterproof frame to create a locally sealed and dry environment. The airbag structure enhances the sealing performance, and an elastic frame and connecting plate are set behind the strain gauge to ensure that the strain gauge is subjected to uniform stress and avoid direct immersion.
It improves the accuracy and stability of test data, enhances the sealing reliability and structural durability of the testing device in underwater environments, ensures stable contact between the strain gauge and the tank surface, and improves the reliability of test results.
