Dynamic Numerical Simulation of Detonation Wave of Perforating Bullet and Research of Its Measuring Method
Dynamic numerical simulation of the spreading of detonation wave was made by use of the explicit dynamic finite element analysis program. The results of numerical simulation are in agreement with physical phenomena and laws of spreading of detonation wave. The study indicates that the calculation model and simulation method are reasonable and feasible. The volume of electronic sensor both at home and abroad is so large that it is difficult to arrange sensing elements in perforating gun. As a result, three-dimensional wave cant be measured. So we approximately substitute the relationship between the mean gun pressure and time. Taking advantage of this measuring method, gun pressure of other styles can be estimated. This is a very valuable method, and may be used for reference to manufacture and scientific research of perforating gun.
