摘要

保证高滴速双事件燃料-空气炸药云爆轰可靠性的关键是使二次起爆装置在分散的燃料中起爆。设计了TDD的弹射机构,并通过外场弹射试验对弹射过程进行了分析。据此,建立了弹射过程的仿真模型,并与实验结果进行了对比,验证了模型的可靠性。在此基础上,给出了两个弹射机构设计优化扩展算例。进一步分析了影响TDD弹射特性的因素,包括弹射装药质量和固定挡板的螺杆参数。本文的研究为高落速defae弹射机构的优化设计提供了理论和实验支持。

Optimization of Ejection Characteristics for Twice-Detonating Device in Double-Event Fuel-Air Explosive with High Drop Velocity
The key to ensure the reliability of the cloud detonation in high-drop-velocity double-event fuel-air explosives (DEFAEs) is to cause the twice-detonating device (TDD) to detonate in the dispersed fuel. Here, an ejection mechanism for a TDD is designed and the ejection process is analyzed through an outfield ejection test. Accordingly, a simulation model for the description of the ejection process is established and verified to be reliable by comparing it with the experimental results. Based on the model, two extended ensamples for design optimization of the ejection mechanism are developed. The factors influencing the ejection characteristics of the TDD are further analyzed, including the ejection charge mass and screw (for baffle fixing) parameter. The research carried out here provides theoretical and experimental support for the optimal design of the ejection mechanism in high-drop-velocity DEFAEs.
