摘要
目前复杂超声场的构建多利用超声相控阵技术,技术复杂、成本较高,本文基于超声悬浮原理,通过改变单轴式超声悬浮系统的反射和发射端的几何形状,利用时域有限差分法研究谐振腔内的声场分布,构建复杂声场,产生了镊子形声场,操作简单容易实现。理论研究结果表明,基于单轴式超声悬浮系统,通过改变发射反射面的形状,可以构建出比较复杂的声场形式,产生具有镊子形声场的超声悬浮系统,并简化超声相控阵的仪器复杂性。
Ultrasonic phased array technology is used for complex ultrasonic field construction. But it is of complex technology, an high cost.. Based on the principle of the acoustic levitation, by changing the shape of the excitation single axis ultrasonic levitation system, the acoustic structures shaped as tweezers is produced surrounding the acoustic levitation regions, the operation is simple and easy to realize. The theoretical analysis indicate that by our convex side single axis acoustic levitation system, we build the complex acoustic structures such as the structure shaped as tweezers and simplify the complexity of the instrument of the ultrasonic phased arrays.
