气态低冲击阻尼式弹上火工作动器研究

Research on High Load Low Impact Damping Onboard Pyrotechnics Actuation Technology

目前国内弹上作动产品较多使用弹簧、扭簧等贮能零件或火工品作用产生的气体所为动力源,在推力、冲击过载等方面分别存在一定的局限性;为了解决该问题,提出了一种基于气体阻尼的作动器,通过调整火药柱的初始质量能够实现弹上火工作动产品大推力、小冲击、速度可控等多方面功能,并且结构简单、体积较小,应用范围广泛。

At present,more domestic onboard actuation products use energy generated by storage components or pyrotechnics such as spring and torsion spring as a power source,but there are some limitations in the thrust and impact overload respectively. This paper proposed a new kind of actuator based on gas damping. It can make the onboard actuation in large thrust,small impact and achieve many functions such as speed controllable by adjusting the initial weight of stick. This product has simple structure,small size and wide range of applications.
