Air-to-air missiles require various impact tests before delivery.The experiments simulated various impact environment during the missile’s life cycle.The range of micro scale experiments for missile landing or launch is lower than the calibration range for domestic minimum impact acceleration.In this paper,shock calibration and vibration calibration are combined.This method solves the problem that the detection sensor used in the micro-scale test cannot trace the source.And this method guarantees the reliability and accuracy of the micro-impact test.
