玻璃酒杯声波激振的原理及其影响因素的探讨

Discussion on Principle and Influence Factors of the Acoustic Excitation of the Wine Glasses

摘要: 本文采用臂力棒模型解释了声波激振的微观机理，并讨论了高阶的振动模式。通过五组实验，探讨液面的高度、液体的密度、黏度、温度和酒杯的尺寸五个主要因素对共振频率的制约作用，结果表明，液面高度、液体的密度与酒杯的共振频率呈负相关，其结果与理论模型较好地吻合；同时发现液体的黏度、温度与酒杯的共振频率呈负相关，且不同尺寸的酒杯对液面高度、液体温度的敏感度不同。

Abstract: In this paper, the arm force rod model is built to illustrate the microscopic mechanism of acoustic excitation and the vibrational modes of higher order are discussed ulteriorly. Five main factors, the height of the liquid level, liquid density, viscosity, temperature and the size of the wine glasses, are analyzed through experiments. The result shows the relationship between liquid levels or its density and frequency of wine glasses are negatively correlated and their value verifies the theoretical model well. Except that, the result also shows liquid viscosity and temperature are negatively correlated with the frequency, and the sensitivity of different size of wine glass to the liquid level and temperature is different.
