Impact of nonlinear friction on frequency response function measurements
This paper discusses the impact of nonlinear friction on frequency response function (FRF) measurements of mechanical systems with nonlinear friction. Having an idea of the level of nonlinear distortion is valuable information for robust linear control design: it allows to estimate the level of accuracy of a linear approximation of the system under consideration. The impact of nonlinear distort...
متن کاملPuckering stick-slip friction induced by a sliding nanoscale contact.
An atomic force microscope reveals that the sliding of a nanotip on a graphite surface occurs through a nanoscale stick-slip mechanism. The angle between the sliding direction and a stiff crystallographic axis determines the periodicity of the slip events defining domains of various friction properties. The experimental data are interpreted using the reaction rate theory, with the energy barrie...
متن کاملSliding Friction Contact Stiffness Model of Involute Arc Cylindrical Gear Based on Fractal Theory
Gear’s normal contact stiffness played an important role in the mechanical equipment. In this paper, the M-B fractal model is modified and the contact surface coefficient is put forward to set up the fractal model, considering the influence of friction, which could be used to calculate accurately the involute arc cylindrical gears’ normal contact stiffness based on the fractal theory and Hertz ...
متن کاملThe motion of a pushed, sliding object : part 2 : contact friction
The physics of motion of a sliding object can be used to plan sensorless robot manipulation strategies based on sliding. Prediction of a sliding object's motion is difficult because the object's distribution of support on the surface, and the resulting frictional forces, are in general unknown. We describe a new approach to the analysis of sliding motion, which finds the set of object motions f...
متن کاملA Triboscopic Investigation of the Wear and Friction of MoS2 in a Reciprocating Sliding Contact
Reciprocating sliding tests with ball-on-flat geometry were performed on a duplex coating at low speeds in moist air (RH=60%). The coating, 55 nm MoS2 on 35 nm of TiN, was deposited by ion-beam assisted deposition onto a steel substrate. Friction coefficient (μ) and electrical contact resistance (Rc) measurements were recorded at ~2μm intervals along the track; these spatially resolved measurem...
