AI Technical Summary

Technical Problem

Traditional technology cannot measure the displacement of the structure in real time during underwater explosion tests, and the water shock fluctuates greatly, making it difficult to quickly calm down and observe the state of the measured object.

Method used

A structural displacement testing device under the action of underwater explosion is designed, including a shell box, a water transfer assembly, a lining plate, a traction assembly, a plate under test, a support assembly and a detection assembly. The water is transported to the water storage chamber through the water transfer assembly. During the test, the water is discharged into the laboratory. The deformation of the plate to be tested is recorded in real time using a pull-line displacement sensor.

Benefits of technology

Real-time testing of structural displacement under underwater explosion conditions is achieved, water resources are saved, and by expanding the laboratory volume and increasing the total water capacity, the fluctuations in water after explosion are quickly calmed down and the risk of overflow is reduced.

Abstract

The invention relates to a structure displacement testing device and method under the action of underwater explosion. Comprising a shell box, a water moving assembly, a lining plate, a traction assembly, a detected plate, a supporting assembly and a detection assembly comprising a stay wire displacement sensor. The lining plate is movably arranged relative to the wall of the shell box through the traction assembly, and the lining plate divides the space in the shell box into a water storage chamber and a test chamber; the supporting assembly is arranged in the test room, a tested plate is arranged on the supporting assembly, and the tested plate is located below the explosion source; the water moving assembly moves water in the water storage chamber into the test chamber during a test, and conveys the water in the test chamber to the water storage chamber after a test stage is completed; the stay wire displacement sensor is arranged outside water and is connected with the tested plate through a stay wire extension line. The device is simple in structure, and achieves the real-time testing of the displacement of the underwater explosion action structure.
