Abstract

Autoparametric resonance in a combined contact (tip apex)–driving-spring (cantilever) system was proposed earlier to explain experimentally observed multiple peaks in friction force as a function of velocity. As shown in this paper, the nontrivial interplay between periodic slips of the tip and initiated vibrations of the cantilever can lead not only to the enhancement of friction but also—what might be even more important in practice—to its substantial suppression. In systems with comparable stiffness of the contact and the driving spring, the autoparametric reduction of friction takes place in a surprisingly wide range of velocities, and it can reach several tens percent, depending on the system parameters and temperature. In this velocity range, frictional energy dissipation exhibits pronounced variations which reflect changes in the character of the contact slips. The key feature of all the changes is that early slips always—in one way or another—prevail over late ones, thus making the registered friction force small with respect to its expected “non-resonant” value.

摩擦抑制与自参数共振

先前提出了接触（尖端）-驱动-弹簧（悬臂）组合系统中的自参数共振，以解释实验观察到的摩擦力作为速度函数的多个峰值。正如本文所示，尖端的周期性滑移和悬臂梁的初始振动之间的重要相互作用不仅会导致摩擦的增强，而且在实践中可能更重要的是对摩擦的实质性抑制。在具有可比较的接触刚度和驱动弹簧的系统中，摩擦的自参数减少发生在一个惊人的宽速度范围内，根据系统参数和温度，它可以达到几十个百分点。在这个速度范围内，摩擦能量耗散表现出明显的变化，这反映了接触滑移特性的变化。所有这些变化的关键特征是，早期滑移总是以这样或那样的方式优于后期滑移，从而使所记录的摩擦力相对于预期的“非共振”值较小。图形抽象
