为了研究RDX基含铝炸药在不同装药直径下的做功能力，进行了Φ25．4 mm和Φ50．0 mm两种尺寸的圆筒试验。试验结果表明，爆轰产物相对比容均为10时，Φ50．0 mm比Φ25．4 mm圆筒的膨胀速度提高约4．73％。此外，基于Lee-Tarver点火增长模型，采用有限元动力学程序LS-DYNA对两种尺寸的圆筒试验进行了数值模拟，并与试验结果相比较，确定了该含铝炸药爆轰产物的Jones-Wilkins-Lee状态方程和反应速率方程参数。
為瞭研究RDX基含鋁炸藥在不同裝藥直徑下的做功能力，進行瞭Φ25．4 mm和Φ50．0 mm兩種呎吋的圓筒試驗。試驗結果錶明，爆轟產物相對比容均為10時，Φ50．0 mm比Φ25．4 mm圓筒的膨脹速度提高約4．73％。此外，基于Lee-Tarver點火增長模型，採用有限元動力學程序LS-DYNA對兩種呎吋的圓筒試驗進行瞭數值模擬，併與試驗結果相比較，確定瞭該含鋁炸藥爆轟產物的Jones-Wilkins-Lee狀態方程和反應速率方程參數。

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.
