摘要基于集总平均经验模态分解（Ensemble Empirical Mode Decomposition， EEMD），提出一种星箭解锁分离机构冲击响应信号分析新方法。通过EEMD，将星箭解锁分离机构解锁过程的冲击信号分解成不同模态分量( Intrinsic Mode Function，IMF)。结果表明前两阶模态分量IMF主要为冲击引起的高频振动，而IMF3之后为冲击激励引起的不同阶固有模态振动和局部振动，并通过模态实验验证了分析的正确性。

Abstract：Based on Ensemble Empirical Mode Decomposition (EEMD), a new method about the shock response analysis of unlocking device of satellite and rocket has been proposed. Shock response signal of unlocking device of satellite and rocket can be resolved into different Intrinsic Mode Functions（IMF）by EEMD. Analyses show that IMFs during the first two phases are high-frequency vibration caused by impacting, while the phases after IMF3 are different modes of vibration and local vibration, which has been verified correctly by the mode experiment analysis.

Key words： unlocking device of satellite and rocket Ensemble Empirical Mode Decomposition (EEMD) Intrinsic Mode Functions（IMF） Shock response
