Abstract To study multi-mechanics composite environmental test technique for multi-axis vibration and shock, through deeply studying test system’s construction, test control scheme and decoupling vibration and shock signals, the signal separation technique was put forward, and the signal separator was designed.The signal separator was taken as an important link of a closed-loop control system to realize decoupling of vibration and shock signals.The separation accuracy of the signal separator reached the expected effect to realize the real-time decoupling and real-time control of vibration and shock signals, and improve the control accuracy of multi-axis shock tests.Through test verification, it was shown that the proposed method is feasible and valuable for practical application.

Key words： Multi-axis Vibration, Multi-axis shock Multi-mechanics test technique combined experiment test technique.
