Abstract
Base on the acoustic levitation technology, concept of contactless transport could be achieved by assembling transducersarray which charged with spatiotemporal modulation of the acoustic field. Our research started with hexagonal-headed ultrasonic transducer design, which was modified by FEM methods to achieve desired amplitude and frequency. A seven sourced hexagonal acoustic array prototype is set to verify the simulation predicted model. Prototype transducers are tested by two-dimensional Doppler vibration system (PSV-300F-B, Polytec co) and precision impedance analyzer (Agilent 9294A), relevant dynamic characteristic parameters are obtained. We verified the suspension and rotation control of the disc by the transducer array through experiments.
在声悬浮技术的基础上，通过装配对声场进行时空调制的传感器阵列，实现了非接触式传输的概念。我们的研究从六边形头部超声换能器的设计开始，通过有限元方法对其进行修改以达到期望的振幅和频率。设置了一个七源六边形声阵列样机，对仿真预测模型进行了验证。采用二维多普勒振动系统(PSV-300F-B, Polytec co .)和精密阻抗分析仪(Agilent 9294A)对换能器样机进行了测试，获得了相关的动态特性参数。通过实验验证了传感器阵列对圆盘的悬浮和旋转控制。
