为考察螺压硝胺改性双基推进剂对机械性激励的安全性，采用无溶剂螺压成型工艺制备了7种RDX含量不同的硝胺改性双基推进剂样品，依据国军标方法研究了含不同RDX的螺压硝胺改性双基推进剂的摩擦感度、撞击感度和枪击感度。结果表明， RDX的加入提高了硝胺改性双基推进剂的摩擦感度和撞击感度，同时增加了其枪击条件下的燃烧概率。

Seven modified nitramine double base propellants with different content of RDX were prepared by screw extrusion process,and their mechanical safety performance, including the friction sensitivity, the impact sensitivity and the shooting sensitivity were studied according to the national military standard methods.Results show that with increasing of RDX, the impact sensitivity, the friction sensitivity and combustion probabilities of shooting of the propellants increase.The friction sensitivity keeps stable at around 60% explosion probability and impact sensitivities increase slowly when RDX content is up to 27%.The combustion probabilities of shooting of the propellant increase with RDX content increasing.
