摘要
作为高稳定频标源的晶体振荡器对振动极为敏感。从振动对晶体振荡器的影响入手,对晶体振荡器的频率振动效应进行了理论方面的研究,推导出了晶体振荡器加速度灵敏度计算公式。为了控制环境振动对晶体振荡器的影响,提出了应用于晶体振荡器的二维隔振系统,并进行了相应的时、频域分析,结果表明该系统具有良好的减振效果,能有效地隔离10 Hz-2000Hz的振动信号。这些分析结果对晶体振荡器的隔振设计有理论上的指导意义。
The oscillator as the ultra-stable standard frequency sources is very sensitive to vibration. In this paper, the influence of vibration on the crystal oscillator is analysed in theory and the acceleration sensitivity formula of crystal oscillation is drawn. A vibration control system with two dimension was proposed to keep the crystal oscillator from the disturbance of environment, and the relative time and frequency domain is analysed. Results of simulations show that the control system can effectively restrain the disturbances whose frequency range form 10Hz to 2000 Hz, These results is significant to guide the design of crystal oscillator vibration isolation system in theory.
