摘　　要：介绍了一种利用液体阻尼效应降低冲击的低冲击火工驱动装置,利用内弹道理论和流体动力学相关知识分析其工作原理,建立了数学模型;通过仿真分析的方法,得到了低冲击火工驱动装置性能参数随时间变化的可视化结果,确定了低冲击的主要控制参数。同时,进行了性能验证试验,试验结果与仿真结果基本—致。本研究为同类产品的设计提供了重要的参考依据。The paper introduces a new type of low shock pyrotechnic actuated device, which uses liquid damping effect to lower shock. Based on interior ballistic technology and hydrokinetic technology, the mathematic model was set up. Through simulation, the visual result has been obtained from the performance parameters which are changed by time, and the main control parameters were determined from the result. At the same time, the verification test was carried out, and the results is accord with that of simulation. The study provides an important reference for the design of similar products.
