| 摘 要： | 在分析音叉受迫振动和共振现象的基础上,利用计算机自动控制与实时测量研究了不同阻尼下音叉的幅频特性和音叉双臂质量与共振频率的关系,测量结果表明振动系统受到阻尼越大,共振时能达到的最大振幅越小,幅频特性曲线的Q值越小,相应的曲线越平缓,音叉双臂质量与其共振频率变化的线性关系较好.

| Abstract: | Based on the analyse of the tuning fork forced vibrations and resonator,Amplitude-frequency characteristics and the relationship between the resonator frequency and double arm’s mass of turning fork under the different damping are studied by the means of the automatic control and real time measurement of computer.The result shows that the greater damping,the smaller the maximum amplitude of resonance and the Q value of amplitude-frequency curve are,and the smoother the corresponding curve is.There is a very... |
