1992年4月3日,航空航天部第一研究院在102所召开了“振动传感器温度响应校准装置”的部级鉴定会,20个单位28名专家、教授出席了会议。经严格认真评审,鉴定委员会一致认为: 1.该装置的振动台采用了新型磁性材料、镶钳式磁路、可加工陶瓷台面以及双排滚轮导向结构等新材料、新工艺,满足了激光绝对校准的要求;测振系统采用了反馈调制式激光仪,解决了高低温环境下测量镜表面氧化脱落和结雾结霜等技术难点,使得激光测振效
On April 3, 1992, the First Research Institute of the Ministry of Aeronautics and Astronautics convened a ministerial appraisal meeting of “Vibration Sensor Temperature Response Calibration Device” at 102 and attended by 28 experts and professors from 20 units. Accredited by the strict and rigorous appraisal committee agreed that: 1. The device shaker using a new type of magnetic material, magnetic circuit with a clamp-type, machinable ceramic countertops and double-row roller-oriented structure and other new materials and new technology to meet the laser absolute Calibration requirements; vibration measurement system uses a feedback-modulated laser instrument to solve the high and low temperature measurement mirror surface oxide shedding and fogging and other technical difficulties, making the laser vibration measurement effect
