这项工作研究了直接超声振动作为辅助颗粒材料穿透的潜在用途。与非超声穿透相比，所需的力被观察到减少了一个数量级。同样，根据所使用的衬底和超声波振幅，总消耗功率可降低27%。还在高重力条件下进行了测试，显示出一种趋势，表明这些好处可以在低重力条件下发挥作用。
This work investigates the potential use of direct ultrasonic vibration as an aid to penetration of granular material. Compared with non-ultrasonic penetration, required forces have been observed to reduce by an order of magnitude. Similarly, total consumed power can be reduced by up to 27%, depending on the substrate and ultrasonic amplitude used. Tests were also carried out in high-gravity conditions, displaying a trend that suggests these benefits could be leveraged in lower gravity regimes.
