摘　　要：文章介绍了微振动对航天器的影响，并基于对微振动计量工作的现实需求，根据现有振动计量技术和设备状态，提出了基于虚拟仪器技术的微振动校准技术研究方案，通过适当量级的振动控制和谐波失真抑制，实现对O．05~400Hz范围内的微振动传感器的校准，提升航天计量保障能力。This paper first briefly discusses the effect of the micro-vibration on spacecraft. Based on the practical demands for the calibration of micro-vibration and the present status of techniques and equipments of the vibration calibration, we come up with a micro-vibration calibration solution. By a proper vibration level control and the harmonic distortion restraint-notch（HDR）, we make the calibration from 0.05 Hz to 400 Hz, which has enhanced our ability to calibrate and complete the launch tasks, and guarantees the sustainable development of our aerospace career.
