彈體底隙超聲檢測方法研究

為了檢測出彈體裝藥與內(nèi)錐面之間底隙的有無，以確保彈體的戰(zhàn)斗性能，本文在超
聲波傳播過程中聲通量守恒原理的基礎(chǔ)上，根據(jù)彈體結(jié)構(gòu)的特殊性，提出一種利用超聲波檢測彈體內(nèi)錐面底隙的方法。通過人工彈體底隙的檢測和對多種型號彈體的實測，表明該方法能夠有效地分辨出底隙和脫膠的有無。該方法對其他錐面上脫粘缺陷的檢測具有借鑒意義。

Abstract: In order to detect whether there is a base gap between the explosive charge and the
inner cone of a shell and ensure its fighting performance, this paper puts forward an ultrasonic
inspection method of base gap based on the principle of conservation of sound flux in propagation and according to the special construction of the shell. Inspection of artificial base gap on the inner cone and actual measurement on shell bodies shows that the method can identify the base gap effectively. The inspection of debonds on other cone may draw lessons from the method.
