在近代通信、导航和识别系统中,频率标准和时钟对加速度的敏感性愈加显得重要。本文就加速度、特别是振动如何影响近代频率标准(晶体振荡器)中对加速度最敏感元件的频率作了指导性论述,介绍了一简单的数学模型,来描述谐和运动对振荡器输出的影啊,证明了加速度灵敏度系数γ具有矢量的特性,提出了加速度灵敏度矢量(?),介绍了振荡器输出的时域、频域特性。这个简单的模型得到了推广,其中包括由于倍频而导致的载波损耗和随机振动。计算了由给定的振动谱引起的相位噪声。指出了一种测量振动灵敏度系数的方法。在以下两个方面评述了现代技术的发展水平:(1把对振动的灵敏度降到最小,2)加速度补偿。
In modern communications, navigation and identification systems, the sensitivity of frequency standards and clocks to acceleration is increasingly important. In this paper, we introduce the acceleration, especially how the vibration affects the frequency of the most sensitive components in the modern frequency standard (crystal oscillator). A simple mathematical model is introduced to describe the effect of harmonic motion on the oscillator output Ah, it is proved that the acceleration sensitivity coefficient γ has a vector characteristic, and the acceleration sensitivity vector (?) Is proposed. The time-domain and frequency-domain characteristics of the oscillator output are introduced. This simple model has been promoted, including carrier loss and random vibration due to frequency doubling. The phase noise caused by a given vibration spectrum was calculated. A method of measuring the vibration sensitivity coefficient is pointed out. The development of modern technology is commented on in two ways: (1) Minimize sensitivity to vibration, 2) Acceleration compensation.
