摘要
通过对音叉振动系统的研究,分析了受迫振动系统振动振幅与驱动力频率的关系及音叉共振频率与双臂质量的关系,并用共振原理设计了振动式液体密度传感器.
This paper analyses the relationship between the amplitude of forced oscillation and the frequency of driving force as well as the relationship between resonant frequency and the mass of the double arm through researching the oscillation of tuning fork. A tuning fork-style liquid density sensor based on resonant oscillation theory is designed.
