防护门快速启动技术研究

The Research on Quick Start Technology of Protective Door

为解决防护门快速关闭的问题,在介绍防护门作用过程的基础上,提出了一种采用炸药爆轰点燃抛射药建立高压的快速启动技术。通过对快速启动系统作用过程的分析,给出了快速启动技术的时间序列组成及时间分配。利用经典内弹道对快速启动技术中的关键时间进行了分析计算。结果表明,采用炸药爆炸的快速点火方式,可以大幅度降低建压燃烧时间,降低幅度在一个数量级以上,可以满足使用要求。

To solve the problem of protective door, the action process of protective door was introduced, and a quick start technolo gy using explosive blast ignition to build high pressure was also introduced. The time sequence and time allocation of the quick start technology were proposed by analyzing the action process of the quick start system. The key time of the quick start technology was analyzed and calculated with the classical ballistics interior. The results indicate that the explosive blast ignition can reduce the pressure-building combustion time largely, and the decreasing extent is more than one order, which can satisfy the requirements. The research result is of great practical value.
