斯蒂芬酸铅/硝化棉含量比对微火工驱动装置做功能力的影响

摘要

Aimed at a kind of micro explosive actuator, the theoretical model of actuation parameters were set up through analysis, and the different matching ratio between the content of LTNR and NC was designed. Meanwhile, the actuation capacity and actuation speed were obtained based on fire test and high speed photography, for the LTNR/NC composition with different matching ratio. The test results indicated that with the increase of NC content, the actuation speed was increased obviously.%针对一种微火工驱动装置，通过理论分析建立了做功参数的理论变化模型，设计了不同配比的斯蒂芬酸铅/硝化棉（1∶0.5，1∶0.10，1∶0.05）装药量，并通过发火试验、高速摄影测试得到了不同药剂配比下装置的做功能力及推杆运动速度。结果表明，随着硝化棉含量的增加，驱动速度明显变大。
