“…The threshold friction F o is equal to µP Pr e , and µ is the friction coefficient of the ballramp contact. [11] As a ball goes into the slipping motion, the lateral friction induced by the ball-ramp remains approximately constant. In this state, the force behavior can be modeled as a spring in series with a slider.…”

For both the vibrating and steady supporting surfaces of a scanning disk in a Besocke-style piezoelectric scanner, a theoretical model is given by considering the nonlinear lateral friction at the micro-contact interface between the positioning legs and the supporting surface. Numerical simulations demonstrate that unexpected flexural vibrations can arise from a vibrating ramp, and their frequencies are lower than the eigenfrequencies of the scanner in the linearly elastic regime. The vibrations essentially depend on 1) the vibrational states of the supporting ramp and the steel ball tips on the three piezoelectric positioning legs, and 2) the tribological characteristics of the contacts between the tips and the ramp. The results give an insight into the intrinsic vibrations of the scanners, and are applicable in designing and optimizing piezoelectric scanning systems.

The contact mechanics model between the stator and the slider of a standing-wave linear piezoelectric driver is established. On the basis of the momentum conservation law, the relation equation between the dynamic contact force and the preload in a period is obtained. Then, the normal contact and tangential friction forces are studied. Considering the gravity of the slider and friction from the guider, the dynamic equations of the slider are established under the start–stop phase, and the effects of the driver parameters on the start–stop characteristics are investigated. The contact models in the steady phase of the driver are derived, and a series of operational characteristics of the driver performance is simulated. Finally, a test is conducted and the analysis results of the validity of the contact model are presented. The contact model is important because it not only helps in predicting and evaluating the performance of the piezoelectric driver but also contributes to the design of these types of drivers.
