分析了粘性液体中共振悬臂梁的特性。在不同浓度的纯水、甘油和乙醇溶液中研究了不同矩形悬臂梁的几何构型，并用附加位移液体质量和液体阻尼力、共振频率和品质因数(Q因子)来描述结果。给出了一组磁致共振悬臂梁在平面外(“弱轴弯曲”)模式下振动的实验结果，并与理论计算进行了比较。这项研究的重要性在于使用共振悬臂梁作为液体环境中的生化传感器。(C)2007 Elsevier B.V.保留所有权利。
The characteristics of resonant cantilevers in viscous liquids are analyzed. Various rectangular cantilevers geometries are studied in pure water, glycerol and ethanol solutions of different concentrations, and the results are described in terms of the added displaced liquid mass and the liquid damping force for both, the resonance frequency and the quality factor (Q-factor). Experimental results using a set of magnetically actuated resonant cantilevers vibrating in the out-of-plane ("weak-axis bending") mode are presented and compared to theoretical calculations. The importance of the study is in the use of resonant cantilevers as biochemical sensors in liquid environments. (c) 2007 Elsevier B.V. All rights reserved.
