| 中文摘要: |
| 空空导弹在产品交付前，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，以解决微小量级冲击试验时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。 |
| 英文摘要: |
| 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. |
