Abstract

The vibration mode of the radiation surface of transducer (or structure of supersaturated cavitation cloud in thin liquid) is investigated experimentally by high-speed photography. The classification of saturated, supersaturated and undersaturated cavitation clouds was proposed, and a comparison was made between saturated and supersaturated cavitation cloud structures in liquid thin layers. The characteristics and formation mechanism of supersaturated cavitation cloud structure were investigated. Based on the close correspondence and rapid response between the distribution of supersaturated cavitation clouds and vibration modes of radiation surface, a new approach is proposed to measure the vibration mode of transducer operating at high power and large amplitude in real time.

摘要

通过高速摄影实验研究了换能器辐射面（或薄液层中超饱和空化云结构）的振动模式。提出了饱和、超饱和和欠饱和空化云的分类方法，并对液层中饱和与超饱和空化云结构进行了比较。研究了超饱和空化云结构的特征和形成机制。基于超饱和空化云分布与辐射面振动模式之间的紧密对应和快速响应，提出了一种实时测量高功率、大振幅工作的换能器振动模式的新方法。
