چکیده
This work presents an investigation on the influence of pitting in EHL rolling contact. The geometry comes as extension architecture for multi-physical numerical calculations element bearing contacts based OpenFOAM. model utilized is built according to state-of-the-art fluid–solid interaction and electro-quasi-static fields. In this framework, contact reduced be two dimensional order reduce computing costs needed. changes electric properties, which are caused by pittings, measured using capacitance put perspective with regard geometry. delivers evaluation how surface degradation, both width w depth d contact, affects properties. It can seen that maximum deviations different radii same structures around 5% would therefore hardly distinguishable corresponding measurements. By comparing data ratio radius, other hand, differences up 50% seen.

An Investigation into Grease Behavior in Thermal EHL Circular Contacts
The behaviors of two lithium lubricating greases were investigated under EHL circular contact through measurements of traction coefficients on a self-made rig in which the contact was continuously fed with fresh grease. The average values of Erying shear stress and shear modulus of the two lithium greases were obtained from traction experimental data using this rig. Based on the Evans-Johnson m...
متن کاملDextrous manipulation with rolling contacts
Dextrous manipulation is a problem of paramount importance in the study of multi ngered robotic hands. Given a grasped object, the main objectives are: (a) generate trajectories for the nger joints so that through the e ects of contact constraints, the object can be transferred to a goal grasp con guration; and (b) derive control algorithms to realize planned trajectories. In this paper, we int...

متن کاملElectrical Capacitance Tomography System
Electrical Capacitance Tomography is a non intruding technique used in industries. It is based on measuring the capacitance of multi-electrode ECT sensor produced by the change in dielectricity or due to change in concentration of material. With the use of computed values, a cross sectional image of the material placed in the dielectric medium is obtained. ECT system can be used in chemical fie...
