本文探讨了超声振动在垂直旋转螺旋钻上的叠加作用。已知超声振动有助于直接穿透颗粒介质,并且可以预期,旋转系统的扭矩要求的任何相关降低都可能改善螺旋钻性能。实验结果表明,相比于非超声波的情况下,超声辅助螺旋钻显着促进颗粒介质的流动,同时适度地减少操作设备所需的扭矩。此外,研究发现,当调整超声波振幅时,颗粒大小、螺旋角和螺旋钻速度都以不同的方式影响螺旋钻的性能。
This paper explores the superposition of ultrasonic vibration on vertical rotating augers in a variety of granular media. Ultrasonic vibration is known to facilitate direct penetration of granular media, and it is anticipated that any related reduction in the torque requirements of a rotating system might improve augering performance. Experimental results suggest that, compared to the non-ultrasonic scenario, ultrasonically assisted augering significantly promotes the flow of granular media, while moderately reducing the torque required to operate the device. Furthermore, it was discovered that particle size, helix angle, and auger speed all affect the performance of the auger in different ways as the ultrasonic amplitude is adjusted.
