Test and Three-dimensional Numerical Simulation of Penetrating Steel Ingot by Linear Shaped Charge with Oval Cover
摘要
Abstract
To study the characteristics and laws of penetrating steel ingot of linear shaped charge( LSC)with oval cover,three-di-mensional numerical model was established by ANSYS /LS-DYNA program. A numerical simulation study was performed,and the actual cutting test was implemented on the base of numerical simulation. By using the method of actual cutting experiment and three-dimensional numerical simulation,the characteristics and laws of penetrating steel ingot of LSC with oval cover were stud-yed. Results show that the cutting depth first increases and then decreases with the standoff increasing. The cutting depth showed insensitivity in a standoff range. The best standoff was 60 mm. The cutting cross shape of the steel ingot of different time was obtained under the different condition of standoff. With the standoff increasing,the cross-section bottom width of penetrating steel ingot was from 55 mm to 75 mm,and the medial depth was from 70 mm to 88 mm,and the both sides depth was from 40 mm to 70 mm. The penetration results of numerical simulation were consistent with the cutting test results. The characteristics and laws of penetrating steel ingot from the simulation model can from the simulation model reflect the actual cutting process.关键词
