Experimental Determination of Oil Rheology Parameters to be Implemented in Power Loss Predictions of Gears and Rolling Element Bearings

April 1, 2019

Rheology models express the way tribological conditions translate to shear stress of the lubricant and friction force on the interacting surfaces. Due to the complexity of the lubricant rheology, the friction coefficient is usually obtained experimentally either under the same operating conditions or by curve fitting in a properly chosen friction map. The current study aims at determining the rheological parameters of a lubricant based on friction measurements carried out on a commercial, readily available ball-on-disc machine.

A New Test Rig to Study Rolling Element Bearing Thermomechanical Behavior

April 1, 2019

Rolling element bearings are widely used in mechanical transmission to reduce friction between two rotating parts. With the further development of the electrical motor in mechanical industry, REBs operate more and more at high rotational speed. For these applications, REBs power losses can be predominant in mechanical transmissions.

Hands-Free Driving in the 1950s

April 1, 2019

Yes, the headline is correct: Autonomous vehicles are not a new idea. In fact, in the 1950s, handsfree driving so interested General Motors engineers that they designed a concept car for it. And in 1956, at its own auto show, the GM Motorama, the automaker unveiled the car, the Firebird II.
