Study on Driving Characteristics of Discrete Rod by Different Initiation Styles
Initiation style can affect detonation wave, with which the movement and shape of rod is controlled deeply. The driving characteristic of discrete rod is investigated numerically by finite element code. Four initiation styles are chosen to analyze the driving rule of the shape and velocity of discrete rod. According to those investigating results, side one-point initiation is the optimal style. In this condition, higher velocity and lower velocity margin are obtained, as well. Compared with other initiation styles, side one-point initiation can improve the damage ability about 10% for the certain requirement.
