Compressor Noise Control Using Shaped Piezo-actuators

对异形压电致动器控制压气机噪声进行了一系列实验和分析研究。通过实验得到了不同形状的压电致动器的等效力、波数和模式耦合特性。建立了一个基于有限元方法的公式来验证这些观测结果。压电致动器安装在家用空调机组中常用的压缩机上，以证明开发的有效性。

A set of experimental and analytical studies is conducted to control compressor noise using shaped piezo actuators. Experiments are conducted to obtain equivalent forces exerted by piezo-actuators, wave numbers, and mode coupling characteristics of different shapes. A finite element method based formulation is developed to verify these observations. Piezo actuators are mounted on compressors commonly used in household air-conditioning units to prove the effectiveness of the developments.
