RDX基含铝炸药不同尺寸的圆筒试验及数值模拟
Different Diameter Cylinder Tests and Numerical Simulation of RDX based Aluminized Explosive
摘要
Abstract
In order to study the power of one RDX-based aluminized explosive with different charge diameter, the cylinder tests with diameters of 25.4 mm and 50.0 mm were conducted.The experimental results show that the expansion velocity ofΦ50.0 mm cylinder is 4.73%higher than that ofΦ25.4 mm when the relative volume of detonation product is 10.By using the dynamic finite element program LS-DYNA, two cylinder tests were simulated and the Lee-Tarver ignition and growth trinomial model was adopted.The parameters Jones-Wilkins-Lee equation of state and the reaction rate of the aluminized explosive were obtained through simulation and test results.关键词
