振动频率对超声触觉表面的摩擦减少的影响已在文献中报道。该模型预测，增加振动的频率导致在恒定的振动振幅下更高的摩擦减少，但这还没有实验报告。在本文中，我们研究了摩擦减少的原型，可以在低（66 kHz）和高（225 kHz）频率振动。通过估计低频下的标准与高频下的样品之间的主观等效点，我们发现高频确实可以减少摩擦，其优点是振动幅度小得多。此外，我们证明了这两个频率条件之间的不变量不是振动振幅。我们的结论是，不变量可以是加速度。
The influence of the vibration frequency on the friction reduction of an ultrasonic haptic surface has been reported in the literature. The models predict that increasing the frequency of the vibration leads to higher friction reduction at constant vibration amplitude, but this has not been reported experimentally. In this paper, we study the friction reduction on a prototype which can vibrate at low (66kHz) and high (225kHz) frequency. By estimating the Point of Subjective Equivalence between a standard at low frequency with a sample at high frequency, we have found that high frequencies can indeed reduce the friction, with the advantage of much smaller vibration amplitude. Moreover, we show that the invariant between the two frequency conditions is not the vibration amplitude. Our conclusion is that the invariant could be the acceleration instead.
