摘　　要：在产品交付前,空空导弹需要做各种模拟寿命周期内经历冲击环境的实验,其中着陆或发射时的微小量级试验范围小于国内最小冲击加速度校准范围。本文采用冲击校准与振动校准相结合的验证方案,解决微小量级冲击试验中所用监测传感器无法溯源的难题,从而保证微小量级冲击试验的可靠性与准确性。Air-to-air missiles require various impact tests before delivery.The tests simulate various impact environment during the missile’s life cycle.The range of micro-scale tests for missile landing or launch is less than the calibration range of 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 be traced to the source.It guarantees the reliability and accuracy of the micro-scale impact test.
