爆炸位置对钛合金定向泄爆容器冲击响应的影响

The reported study focuses on the investigation of the impact response of a titanium alloy directional detonation container when it is subjected to explosives at different positions. Through experimental and numerical simulation studies, the explosion resistance of the container and the flight angle of the impact plug are investigated when 100 g of TNT is placed in different positions. In order to restrict the motion of the container, the axial force on the container is analyzed. The results show that the container undergoes elastic deformation when the explosive is located on the axis. When it is in close contact with the middle of the inner wall, the outer wall of the container bulges and cracks. When it is in close contact with the near end of the inner wall, the outer wall of the container protrudes. Under the action of 100 g of TNT, the average velocity of the impact plug outlet is 124.45 m/s, and the maximum deviation angle is 2.3°. The explosive position has little influence on the velocity of the plug outlet. When the explosive is located at the front and rear ends of the axis, the axial force increases by 173% and 116%, respectively, compared to that when the explosive is located at the center of the axis. The study can provide reference to the design of directional detonation container and connection structure of civil aircraft.
