Abstract

In this paper, the simulation technology is used to simulate the higher acceleration peak of the specimen with the hope of Golden Sen. The double cone bullet is used as the experimental device, the simulation results show that with the same bullet velocity impacting the compression rod, the acceleration peak of the specimen increases with the increase of the middle diameter of the double cone bullet, and the acceleration pulse width of the specimen is invariable. The acceleration peak value of the specimen obtained by increasing the surface diameter and the intermediate diameter of the projectile is greater than that of increasing the surface diameter and the length of the projectile.

Key words： Hopkinson strut; double-tapered bullet; numerical simulation; acceleration-time curve
