| 摘 要： | 采用小隔板试验(SSGT)测定了主体炸药黑索今(RDX)粒度和粒度级配对不同密度的RDX/F2641(95/5)高分子粘结炸药冲击波感度的影响，RDX粒度范围为1～150 μm，试验的炸药密度为80%、90%和95%理论密度。结果表明随RDX平均粒度的增大，混合炸药冲击波感度提高，但不同密度时，影响程度有所不同。在本试验条件下，试验结果主要反映了炸药粒度对热点点火过程的影响。

| Abstract: | The influence of particle size and gradation of RDX particles on the shock sensitivity of a polymer bonded explosive RDX/F2641 (95 /5) with different dencities was experimentally investigated by small scale gap tests, In this study, the particle size of RDX is changed from Iμm to 150 μm, densities of the compos?ite formulation are 80% , 90% and 95 % TMD. Generally, shock sensitivity decreases with the increase of mean particle size of RDX, but the tendency of influence in different dencities are different. The results mainly represent the effect of particle size of explosive on the hot spot ignition under test conditions. |
