运用统计能量分析法预示空空导弹舱内动力学环境

空空导弹在挂飞过程中会遇到多种冲击和振动环境的作用，对导弹结构及其内部设备的性能影响不可忽视。针对某型空空导弹，利用稳态统计能量分析法对其包含机动抖振的随机振动环境进行预示，同时采用基于冲击响应谱的瞬态统计能量分析法预示导弹设备舱内的高频冲击环境。计算仿真与实测结果比较表明，统计能量分析法能够较为准确地预示动力学环境。

PREDICTING DYNAMIC ENVIRONMENT OF AIR TO AIR MISSILE MODULE WITH STATISTICAL ENERGY ANALYSIS METHOD

An air to air missile is affected by manifold shock and vibration environment when its captive carriage is flying.Their effects on the missile structure and the performance of its inboard devices can not be ignored.For one type air to air missile,the stationary statistical energy analysis(SEA) method is used to predict its random vibration environment including mobile shake,and the transient SEA based shock response spectrum(SRS) is used to predict its high frequency shock environment inboard.The comparison of the simulated results with those obtained by tests shows that SEA can predict dynamic environment a little bit exactly.
