Contact stiffness of randomly rough surfaces
We investigate the contact stiffness of an elastic half-space and a rigid indenter with randomly rough surface having a power spectrum C2D(q)proportional q(-2H-2), where q is the wave vector. The range of H[symbol: see text] is studied covering a wide range of roughness types from white noise to smooth single asperities. At low forces, the contact stiffness is in all cases a power law function ...
متن کاملNon-Contact Stiffness Measurement of a Suspended Single Walled Carbon Nanotube Device
A new nanoscale electric field sensor was developed for studying triboelectric charging in terrestrial and Martian dust devils. This sensor is capable to measure the large electric fields for large dust devils without saturation. However, to quantify the electric charges and the field strength it is critical to calibrate the mechanical stiffness of the sensor devices. We performed a technical f...
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 کاملA method for stiffness tuning of machine tool supports considering contact stiffness
A methodology for tuning the stiffness of machine tool supports is described based on a stiffness model using the contact stiffness approach. Using this model, the mathematical relationship between the load of the support and its stiffness is established. The relationship is separated into three regions. When the total stiffness of all supports is maximized, the load must be tuned so that the s...
متن کاملHaptic-Auditory Rendering and Perception of Contact Stiffness
This paper presents an experiment on the relative contributions of haptic and auditory information to bimodal judgments of contact stiffness using a rigid probe. Haptic feedback is rendered via a Phantom R © Omni device, while auditory stimuli are obtained using a physically-based audio model of impact, in which the colliding objects are described as modal resonators that interact through a non...
