With the people's understanding of cavitation phenomenon advancing continuously, cavitation dynamics is gradually applied in medical scenarios such as clinical treatment and clinical testing. In clinical treatment, the high-speed jet generated when the cavitation bubble collapses is the important factors of the tissue damage. The interaction between a single cavitation bubble and the elastic boundary has an important impact on the understanding of the tissue damage. Carrying out the basic research on the interaction between cavitation bubble and elastic boundaries is of great significance for optimizing practical applications and improving the stability and reliability of cavitation treatment. However，the literature surveies show that the current research on the dynamic mechanism of the interaction between single cavitation bubble and elastic boundary is unclear. Therefore, systematic study on the interaction mechanism between a single cavitation bubble and elastic boundaries is carried out in this paper by means of experiments and dimensional analysis. The main work is as follows: Firstly, the experiment methods and dimensional analysis are introduced in detail, including the establishment of an experimental observation system for the interaction between cavitation bubbles and elastic boundaries based on high-speed photography and electrode position fine-tuning device. Three dimensionless parameters that influence the interaction between cavitation bubblee and elastic boundaries, including dimensionless density, dimensionless distance and dimensionless thickness, are determined on the basis of dimensional analysis methods. Secondly, according to the elastic modulus of the elastic boundary, this paper carried out experimental research on the interaction between a single cavitation bubble and different modulus of elastic boundaries, and recorded the pulsating behavior of the cavitation bubble and the elastic boundary response when the dimensionless distance and thickness change. Finally, on the basis of the experimental results, this paper establishes the jet type and elastic boundary pierce hase diagram with the dimensionless distance between and the dimensionless thickness as the basic parameters and analyzes the mechanism of different jet types and the puncture mechanism of jet-induced elastic boundary after cavitation bubble collapse. Meanwhile, The effect of dimensionless distance and dimensionless thickness on boundary deformation is discussed. The research results of the thesis show that the elastic boundary thickness and the distance between the cavitation bubble and the elastic boundary will affect the magnitude and position of the additional pressure on the cavitation bubble generated by the elastic boundary constraint and rebound, which is the potential mechanism of jet generation and then affects the shape of the jet. The elastic boundary deformation decreases with increasing dimensionless distance and decreases with increasing dimensionless thickness. The dimensionless distance and the dimensionless thickness of the boundary are important parameters of boundary penetration.. To sum up, this paper conducts a systematic study on the interaction behavior and mechanism of a single cavitation bubble and different types of elastic boundaries, improves the understanding of the interaction between cavitation bubbles and elastic boundaries and plays an important role in solving the problem between cavitation and human tissue in clinical practice.
