为了检测出弹体装药与内锥面之间底隙的有无，以确保弹体的战斗性能，本文在超
声波传播过程中声通量守恒原理的基础上，根据弹体结构的特殊性，提出一种利用超声波检测弹体内锥面底隙的方法。通过人工弹体底隙的检测和对多种型号弹体的实测，表明该方法能够有效地分辨出底隙和脱胶的有无。该方法对其他锥面上脱粘缺陷的检测具有借鉴意义。

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.
Key words: shell; base gap; conservation of sound flux; ultrasonic inspection
