摘　　要：描述一种使用单轴式换能器和双反射面的声悬浮器来实现固体小球在空气中悬浮传输的方法。通过调节上下两个反射面之间的距离,实现聚苯乙烯小球在声悬浮器声场中的水平悬浮传输,小球的传输距离为28.2 mm。文中对两个反射面不同间距下悬浮器声场内的声时间平均势分布和悬浮位置的变化情况进行有限元仿真分析和实验研究。悬浮小球沿水平方向传输路径的数值预测结果与实验结果吻合良好,仿真模型可以被用来有效地预测小球的悬浮及运动轨迹。The paper presents here a method to transport solid particles in air by using an acoustic levitator with a single-axis transducer and double reflectors.The polystyrene particle is levitated and transported 28.2 mm horizontally in acoustic field of the acoustic levitator by regulating the distance between two reflectors.The distribution of acoustic time-averaged potential and the position of levitation at different distance between two reflectors inside the acoustic levitator chamber was studied with finite element simulations and experiments.Numerical predictions of the translation path of levitated particles along the horizontal direction show good agreement with the experimental results.The model of simulation can be used to predict the position and the translation trajectory effectively.
