| 摘 要： | 火工作动筒是利用燃药的爆燃压力作为动力源的火工装置,燃药在燃烧的瞬间会产生一个压力脉冲,这是火工装置中存在的普遍现象,压力脉冲形成的冲击载荷会对作动筒的结构强度产生一定的影响,本文对这种影响进行了分析和试验验证。结果表明对作动筒结构强度产生影响的因素是压力脉冲的幅值和脉冲宽度的积,文章提出了对火工作动筒的强度安全性能的评估方法。

| Abstract: | Pyro-actuator is a device that uses deflagrated pressure gas as power source, powder bring a pressure pulse as it burned instantly, the phenomena occurs in pyro-device generally. Pressure pulse conduces to an impact on pyro-actuator and it will affect the intension ofpyro-actuator. The article analyses the effect and test it, the test results show that the product of amplitude and time is the real factor to affect intension of pyro-actuator. The article puts an evaluating method on intension-safety ofpyro-actuator. |
