Single axis ultrasonic levitation system with a circular clamping force

  • 摘要: 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,利用凸状发射、反射面在悬浮区域周围产生环形声辐射力势阱作为限位夹持力,提高悬浮样品在驻波声场中的悬浮稳定性。基于时域有限差分法,研究不同谐振腔内的声辐射力分布,以及影响声辐射力大小的因素,优化环形限位夹持力和悬浮力。理论及实验研究结果表明,具有环形限位夹持力的超声悬浮系统可以提高普通单轴式超声悬浮装置对悬浮样品的稳定性。
    Abstract: Based on the principle of the acoustic levitation, by changing the shape of the excitation and the reflection side of tile single axis ultrasonic levitation system to convex, the circular clamping force is produced surrounding the acoustic levitation regions, and the stability of sample suspension is improved in the standing wave field. By tile Finite Difference Time Domain (FDTD) method, we studied the force distribution in different resonant cavity, tile factors affecting of the suspension force, and optimized the circular clamping force and the suspension force. The experiment results and theoretical analysis indicate that the stability of the ordinary single axis acoustic levitation system can be improved by the circular clamping force of our convex side system
