摘　　要：为研究弹体结构设计对弹体装药起爆可靠性的影响,设计了一种低成本、便捷式引战静态匹配试验装置,开展了不同条件下引信与装药的传爆裕度试验。基于移动最小二乘法,构建了可表征起爆可靠性的多变量响应函数,定量分析了各敏感因素及其耦合作用对起爆可靠性的影响规律。结果表明:传爆间隙和缓冲层厚度对弹体装药起爆影响较大,而隔板厚度在预设3~5 mm范围内的影响较小;为保证动能侵彻弹在使用环境温度范围内可靠作用,引信相对偏离位置、隔板厚度、传爆间隙以及缓冲层厚度分别不应超过25、3.5、25以及22 mm。该试验装置、分析方法及研究成果可为动能侵彻弹结构设计及可靠性验证提供借鉴和指导。In order to investigate the influence of projectile structure design on the detonation reliability,a low-cost and portable static test device for fuze-warhead coordination is designed in this paper to carry out the tests of detonation transfer margin under different conditions.Based on the moving least square method,the multivariable response function is constructed to evaluate the detonation reliability and quantitatively analyze influence of the sensitive factors and coupled effects.The results indicate that the gap distance and the thickness of inert buffer layer have more significant impact on the detonation of the warhead charge while the influence of the interlayer thickness is relatively small within the preset range of 3-5 mm.To ensure the reliability of kinetic energy penetrators under ambient temperature,the relative position of fuze,the interlayer thickness,the gap distance and the thickness of inert buffer layer should not exceed 25,3.5,25,and 22 mm,respectively.The test device,analysis method and research results will provide a good reference and guideline for structural design and reliability verification of kinetic energy penetrators.
