Calibration of frictional forces in atomic force microscopy
The atomic force microscope can provide information on the atomic-level frictional properties of surfaces, but reproducible quantitative measurements are difficult to obtain. Parameters that are either unknown or difficult to precisely measure include the normal and lateral cantilever force constants (particularly with microfabricated cantilevers), the tip height, the deflection sensor response...
متن کاملPerturbation Stability of Frictional Sliding with Varying Normal Force
In many systems, the normal force at friction contacts is not constant, but instead is a function of the system's state variables. Examples include machine tools, friction dampers, brake systems and robotic contact with the environment. Friction at these contacts has been shown to possess dynamics associated with changes in normal force. In an earlier paper, the authors derived a critical value...
متن کاملStability of Sliding Frictional Surfaces with Varying Normal Force
This paper presents the stability analysis of a single degree of freedom elastic system following a rateand state-dependent friction law. Normal force is assumed to depend on the displacement, velocity and acceleration of the sliding interface. The history dependence of friction on normal force is included in the analysis. It is shown that to achieve steady sliding, system sti ness must exceed ...
متن کاملFrictional Behavior of Individual Vascular Smooth Muscle Cells Assessed By Lateral Force Microscopy
With the advancement of the field of biotribology, considerable interest has arisen in the study of cell and tissue frictional properties. From the perspective of medical device development, the frictional properties between a rigid surface and underlying cells and tissues are of a particular clinical interest. As with many bearing surfaces, it is likely that contact asperities exist at the siz...
متن کاملModeling rectangular cantilevers during torsion and deflection for application to frictional force microscopy.
A numerical and experimental analysis of the optical beam deflection system used to monitor microcantilevers subjected to simultaneous deflection and twisting such as in lateral or frictional force microscopy was performed. This study focused on two optical beam deflection orientations where in the first case the optical beam and the detector are at a right angle to the length of the cantilever...
