摘要: 提出了烟火药水下燃烧有效作用时间的概念,分析了当前烟火药水下燃烧和水下爆炸等声辐射特性的测试手段和处理方法的不足。基于Pulse Labshop软件平台,结合实验结果,采用图形切片方法,获得了有效作用时间,解决了烟火药水下燃烧或水下爆炸等声源有效作用时间的评价问题,为工程应用和性能评价提供了一种方法。Abstract: The defining of effective acting time for pyrotechnic composition combustion underwater was put forward. The main problems of current methods for testing and processing the acoustic radiation characteristics of pyrotechnic composition combustion underwater and explosion underwater were analyzed. And then, based on Pulse Labshop software platform and experimental results, the effective acting time for pyrotechnic composition combustion underwater was obtained, with graphic slicing technique. This new method can be used to assess the effective acting time of pyrotechnic composition combustion underwater and explosion underwater sound source, and so on. It also provides a reference for the engineering application and performance evaluation.
