Background
In the test of the compressive strength of a test material, an acoustic emission probe needs to be installed to collect data to represent the degree of crack damage. When the test piece is small in size, the number of probes is large (such as 4 probes up and down) and manual installation is difficult and time-consuming. In addition, the probe is easy to slip, slide or misplace, and the position of the probe is inconsistent with the preset. These factors can affect the positioning accuracy and accuracy of the acoustic emission data, thereby affecting the observation and analysis of crack damage and crack growth, and causing failure or inaccuracy in acquisition of the target experimental data.
The positioning accuracy of the acoustic emission detection is independent of the geometry of the probe itself. However, the area covered by the probe array is large and the accuracy of the probe position directly affects the accuracy of the positioning source. Therefore, in acoustic emission detection, the arrangement mode of the isosceles or equilateral triangle probe should be selected preferentially, and the accuracy of probe placement is ensured. In the process, the auxiliary positioning device is used for fixing the acoustic emission probe, so that the test efficiency can be effectively improved.
