摘　　要：动态压力校准技术是确保航天型号压力测试数据准确可靠、量值统一的关键。介绍了动态压力校准的必要性和特殊性,分别从阶跃压力校准法、周期压力校准法以及脉冲压力校准法三个方面,系统总结了国内外动态压力校准技术的研究现状,提出目前仍存在的问题并对未来动态压力校准技术的发展提出改进措施。Dynamic pressure calibration technology is the key to ensure the accuracy,reliability and uniformity of the pressure test data of aerospace models.The necessity and particularity of dynamic pressure calibration are expounded.The research status of dynamic pressure calibration technology at home and abroad is summarized systematically from three aspects:step pressure calibration method,periodic pressure calibration method and pulse pressure calibration method.The existing problems at present are pointed out and the improvement measures for the future development of dynamic pressure calibration technology are put forward.The measures suggested that laser interference technology should be applied to dynamic pressure calibration,and the nation standard of dynamic pressure should be established,which consists of step pressure calibration device,sinusoidal pressure calibration device and pulse pressure calibration device.
