Thus, the introduction – into a polymer – of additives that alter its physical structure, unavoidably affects the triboengineering properties. The tribochemical transformations in macromolecules and wear of the polymer can be affected by the metal composition of the counterface. The role of this...
or limiting friction. rolling friction is often a combination of several types of frictions acting between the point of contact of the curved surface and the ground. notice that it is not always necessary that a wheel or a sphere will roll. it may slide depending upon its motion, and the ...
Surface adsorptivity normally increases with increasing polarity of the additive, while thickness of the adsorbed film increases with increasing its viscosity (related to average molecular weight). However, excessive polarity and viscosity undermine miscibility of the additive with (hydrocarbon) base stocks...
The oil consumption in the engine and its impact on the PM emission was estimated. The additional arrangements facilitating the extrapolation of the obtained friction results to the cases of using other oils and the method of measuring the PM emission on the test stand were proposed....
All recordings and stimulus deliveries were controlled using Spike2. These signals were displayed on-line during the experiment. Figure 1 Experimental set-up and unit locations on the hand. (a) Stimtac unit mounted on the robot platform and its adjustable mount. (b) Locations of the centers ...
A time lag between the sliding speed and resulting friction was proposed to describe the observed friction hysteresis. Two different types of lag were considered: (i) a constant time lag independent of the sliding speed and (ii) a time lag inversely proportional to the sliding speed. The ...
While the invention and its alternate variation solutions has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those in the art that the foregoing and other changes in form and details may be made therein without departing from the spiri...
The type is then instantiated (populating all of its dependencies using the same mechanism) and passed in to the constructor.However, you can configure the injector to use types that differ from the parameter name, or return existing objects....

Dynamic friction is the only mechanical element that dissipates energy and, as with the resistor, that energy is converted to heat. The force-velocity relationship for a friction element is also similar to a resistor: the force generated by the friction element is proportional to its velocity: ...
