Abstract

The invention belongs to the technical field of nondestructive detection and particularly relates to a Ti-Al series alloy shaped charge liner structure consistency detection device and detection method. The Ti-Al series alloy shaped charge liner structure consistency detection device comprises a support rod, an impact force applying part and an audio signal acquisition part which are arranged beside the support rod in use, and signal processing software electrically connected with the audio signal acquisition part. According to the invention, the Ti-Al alloy shaped charge liner placed on the support rod makes a sound by using the impact force applying part; the characteristic frequency of the Ti-Al series alloy shaped charge liner is obtained through the audio signal acquisition part and the signal processing software, and based on the audio detection technology, the characteristic frequency is compared with the standard frequency of a standard Ti-Al series alloy shaped charge liner such that the nondestructive detection of the quality of the Ti-Al series alloy shaped charge liner is realized.

Description

technical field [0001] The invention belongs to the technical field of non-destructive testing, and in particular relates to a detection device and a detection method for the consistency of the structure of a Ti-Al alloy liner. Background technique [0002] In the process of oil and gas exploitation, whether the quality of the liner is qualified or not directly determines the perforation effect of the perforating bullet. At present, the quality inspection of perforating bullets in industrial production mainly relies on manual measurement of the wall thickness of the liner, and its shape inspection; to determine whether the internal structure of the liner is consistent, it is necessary to sample the liner for destructive testing. This detection method generally has the problems of low measurement accuracy, low detection efficiency, and low reliability. In terms of improving the detection efficiency of drug masks, ensuring the quality of drug masks, and realizing 100% detecti...
