建立了发射药粒在动态载荷下的挤压破碎过程动力学模型并进行了数值计算，基于发射装药挤压破碎试验装置，研制了挤压应力PVDF传感器，并进行了发射装药动态挤压应力试验。数值模拟结果与试验结果吻合较好，验证了数学模型的正确性和新型传感器设计的合理性，说明新型传感器可以用于发射装药挤压破碎试验中对发射装药颗粒间挤压应力的测量。

The processing characteristics, microstructures andmechanical properties of the azide nitramine gun propellant and double-base gunpropellant which were both prepared with a method free of volatile solvent werestudied by means of a two roller calendar, SEM and tensile strength tester. Theresults indicate that the rolling and plasticizing temperature, plasticizingtimes and molding pressure of the azide nitramine gun propellant for the highnitrogen contents(12.6%, 13.0%) of NC are lower than those of the double-basegun propellant. DIANP(1,5-Diazido-3-nitrazapentane) can efficiently plasticizethe high nitrogen content of NC, the mechanical properties of the gunpropellant with DIANP are excellent within a wide range of temperature. Theplastication of DIANP on the high nitrogen content of NC is better than that ofNG, this can contribute to the gun propellant with a satisified flexibility andan improved low temperature mechanical properties.
