Abstract Based on the dynamic load identification principle in the frequency domain method,impact loads of a connection-separation device between satellite and rocket driven using shape memory alloy (SMA) were identified for three times. The EEMD algorithm was used to de-noise and identify impact response signals of measured points,and then three times of impact loads generated in separation process were identified. The test results showed that the frequency domain method based on EEMD can be used to more accurately identify three times of impact loads of the connection-separation device between satellite and rocket with a better recognition effect,the feasibility and correctness of the proposed method is also verified with test results.

Key words： connection-separation device impact load parametric identification frequency domain method ensemble empirical mode decomposition (EEMD)
