| 目的空腔共鸣噪声环境是新一代战斗机内埋武器遇到的严酷的使用环境之一，需要对内埋武器在空腔共鸣环境下的噪声试验方法进行研究，以提高其环境适应性。方法分析噪声环境对内埋武器的影响和GJB150.17给出的三种噪声试验方法，重点讨论在没有实测数据时确定空腔共鸣频率的计算方法。结果GJB150.17给出的空腔共鸣频率计算结果存在偏差，新噪声试验标准对空腔共鸣频率计算公式进行了修正，典型空腔结构的1阶模态共鸣频率提高到45Hz以上。结论给出可操作的内埋武器空腔共鸣噪声条件和试验程序。 |

| ObjectiveCavity resonance acoustic noise is a rigorous service environment of new-generation aircraft internal captive weapon. The aim of this paper is to study the cavity resonance acoustic noise test method for internal captive weapon.MethodsAcoustic noise environment infection on internal captive weapon and three test methods of GJB150.17 were analyzed，and the calculating method of cavity resonance frequency was majorly discussed without measured data. ResultsThere were some deviations from the calculating result of cavity resonance frequency by GJB150.17，which was amended in the new acoustic noise test standard. The first mode cavity resonance frequency of typical cavity structure was improved to above 45Hz.ConclusionA feasible cavity resonance acoustic noise test condition computing method and test program of internal captive weapon was presented. |
