Using the loading technique of electrically exploding driven the kapton flyer to produce with short-duration pulse shock wave, the shock initiation threshold of a nanometer TATB/B based explosive under the condition of 50% initiation probability has been obtained by means of the DRM (Delayed Robbins-Monro) test procedure.

In this paper,a kind of metal material is presented,it makes the cost of the flyer impact initiation detonation experiment much lower than before and provide the availability for people to study the impact initiation mechanism of explosive.

The fragment impact initiation of the charge covered with a thin plate was researched.

Based on an analysis of the shock initiation theory of explosives,the annular structure booster pellet and the annular conical structure booster pellet were designed.

In order to meet the requirement of insensitive ammunition,the concave-spherical booster pellet and hemispherical booster pellet are designed based on shock initiation theory,and the initiation capacity of the new booster pellet structure is compared with that of the regular cylinder booster pellet.

Based on the one-dimensional energy criterion of explosives shock initiation,considering the shock propagation of projectile impacting covered explosives,the relation formula of threshold velocity is obtained as Vw≈0.

Based on the theory for coupled vibrations of master-slave systems,by choosing shipboard supercharged boilers and gear cases as research objects,the numerical statistical characteristics of numerical experiments for ship hull and equipment integrated analysis were discussed to determine the anti-shock threshold values of shipboard equipments.
