摘要

目前的研究是通过焦耳加热预测电阻分流梁的压电阻尼。为了使压电分流梁系统的附加阻尼最大化，对其进行了灵敏度分析。研究了不同长度和厚度比下PZT-5H与悬臂和简支梁底部的位置对最大附加阻尼模拟的几何影响。在进行灵敏度分析之前，要建立一个数学模型，用于根据产生的电压估计额外阻尼。还进行了验证实验。

Sensitive analysis on added damping of shunted piezoceramic damping: cantilever and simply supported beam

The current research investigates the prediction of piezoelectric damping of resistively shunted beams caused by resistors via joule heating. In order to maximize the extra damping of the piezoelectric shunted beam system, a sensitivity analysis was done. The geometrical impacts on the maximum additional damping simulation are investigated for different length and thickness ratios with the position of the PZT-5H from the base of the cantilever and simply supported beams. Prior to doing sensitivity analysis, a mathematical model for estimating extra damping from voltage produced. Validation experiments are also carried out.
