摘要通过电火花气泡装置和高速摄像设备对气泡与附近刚性/柔性边界间的耦合现象进行实验观测和研究。针对不同材质平板和不同距离参数下气泡脉动实验数据进行整理，对气泡动力学特性如撕裂现象、射流方向特性及气泡迁移特性等进行机理分析；并借助MATLAB开发图片数字化识别程序，分析总结了整个气泡脉动载荷下柔性板的整体运动响应模式和结构中心测点的响应特征。实验结果表明：气泡在柔性板附近收缩时出现“棒槌”状或气泡撕裂及远离对向射流现象；探究气泡载荷下柔性结构响应模式，发现气泡膨胀时柔性板呈一阶响应，收缩时呈现三阶响应及双峰值迁移现象。

Abstract：

Coupling phenomena between bubble and neighboring rigid/flexible boundaries were tested, monitored and studied using an electric spark air bubble device and a high-speed camera. The bubble pulse test data under conditions of flat panels of different materials and different distance parameters were collated to perform mechanism analysis for bubble dynamic characteristics including bubble splitting phenomenon, bubble jet direction property and bubble migration features, etc. The software MATLAB was used to develop an image digital recognition program. A flexible plate’s overall motion response mode under the whole bubble pulsation load and the structure center measured point’s response features were analyzed and summed. The test results showed that when bubble contracts near a flexible plate, bubble changes into a "wooden club" shape or splits into two small ones, and jets away from opposite directions occur; the motion response mode of the flexible plate under the whole bubble pulsation load is explored, the flexible plate reveals the one-order response mode during bubble expanding, while when bubble contracts, the plate reveals the third-order response mode and two-peak values migration phenomenon.
