In response to the problem of defective ring fracture behavior under the effect of detonation superposition,theoreti-cal analysis was conducted on the propagation process of detonation waves in charge containing waveform regulator.The range of waveform regulator thickness values was determined.Based on the designed warhead structure,numerical simulation valida-ted by experiment was used to study the influence of skin parameter,waveform regulator parameters,rectangular notch param-eters,and explosive types on the fracture behavior of defective ring under the detonation superposition effect.The result show that the waveform regulator can achieve multi-source synchronous detonation superposition and act on the ring.The ring can fracture simultaneously at the position of the detonation wave superimposed pressure(M position)and rectangular notches(D position).The increase of either the relative thickness of the skin,the relative depth of the notch,or the relative width of the notch will be unfavorable to the fracture of the M position,while the increase of either the detonation wave superimposed pressure,the relative spacing of the notch,or the curvature radius of the detonation wave acting on the D position will be conducive to the fracture of the M position.When the skin relative thickness is 0,the notch relative width is 0.015,the notch relative spacing is 0.45-0.88,the slot relative spacing is 0.39-0.77,the slot relative width is 0.1-0.167,the charge type is Comp B explosive or Octol explosive,and the notch is located on the outer wall of the ring,the ring can fracture at po-sitions M and D with a large damage power at the same time.
