摘要:
提出了一种新的评价高能发射药动态力学强度的方法，即采用落锤撞击发射药粒，用药粒发生临界损伤时的撞击能和极限抗冲应力来表征发射药的动态力学性能。结果表明，该方法能够定量评价发射药的动态力学强度，并得到太根药、硝胺药、硝基胍药等3种发射药的临界撞击能分别为18.8 J/cm2、14.2 J/cm2、3.8 J/cm2，极限抗冲应力分别为247.2 MPa、214.2 MPa、118.5 MPa。
Abstract:
A new evaluation method of dynamic strength of high energy propellants was proposed. Dynamic mechanical property of the propellants is characterized by the critical impact energy and the limit impact stress when the critical damage to the granular propellants by a dropping hammer occurs.Results indicate that the evaluation method can quantitatively reflect the dynamic mechanical strength of the propellants. The critical impact energy of TEGDN propellant, nitramine propellant and nitroguanidine propellant is 18.8 J/cm2,14.2 J/cm2 and 3.8 J/cm2, and the limit impact stress 247.2 MPa,214.2 MPa and 118.5 MPa, respectively.
