Bar Vibrational Modes巴 振动模式
 The elastic property involved in the vibration of bars is usually stated in terms of Young's modulus. 杆的振动所涉及的弹性性质通常用杨氏模量来表示。

Clamped Bar Modes固定端杆的模态
The frequency f1 depends upon the density and elasticity of the material from which the bars are made. The amplitudes for the f2 and f3 modes would actually be much smaller than the fundamental. These mode frequencies appear with a tuning fork since it can be considered to be two clamped bars. 频率 f₁ 依赖于制成音叉材料的密度和弹性。f₂ 和 f₃ 模式振幅实际上会比基频小很多。这些模态频率出现在音叉中，因为可以将其视为两个夹紧的棒。

Free Bar Modes自由巴模式
The frequency f1 depends upon the density and elasticity of the material from which the bars are made. The amplitudes for the f2 and f3 modes would actually be much smaller than the fundamental. 
频率 f₁ 依赖于制成棒材的材料的密度和弹性。f₂ 和 f₃ 模式的振幅实际上会远小于基频。 |
