摘要: 在前入水下爆炸实验研究的基础上,引入柱形和球形装药的修正因子,建立了炸药水下爆炸气泡脉动周期的工程计算方法,揭示了炸药爆热与水下爆炸气泡脉动周期的关系,通过实验进行了验证,其计算误差小于5%,实现了不同炸药、不同装药结构水下爆炸气泡脉动周期准确的计算。该计算方法的建立为水下炸药配方设计、水中炸药性能评估提供重要的科学依据。

Abstract: Based on the experiment research of former scientists, an engineering calculation method on the bubble pulse period of underwater explosion was established by introaucing the correction factors of cylindrical and spherical charge forms into the relationship between explosion heat and bubble pulse pe?riod was revealed, and the exact calculation was realized by the method at the different explosives and charge forms. The method was verified by an experiment. The error of results between the experi?mented and the calculated is smaller than 5 % . The method provides important science basis for design?ing formulation and evaluating performance of underwater explosive.

Key words: mechanics of explosion , underwater explosion , bubble period , explosion heat
