For road vehicles, wind resistance increases fuel consumption. But one way to fight wind is with wind. Researchers in Sweden are experimenting with reducing drag on trucks with electric wind devices that mimic the way […]
It is a common trope in disaster movies: an earthquake strikes, causing the ground to rip open and swallow people and cars whole. The gaping earth might make for cinematic drama, but earthquake scientists have […]
In a rolling bearing, the load transmission is often accompanied by high contact stresses which may eventually lead to wear and/or fatigue. In order to ensure separation of moving parts leading to a long life, […]
Lip seals compete with mechanical face seals in sealing oil or grease in rotary shaft applications. Under certain running conditions both kinds of seals can be used however, the latter ones are generally used for […]
September 1 of 2016 at Cape Canaveral SpaceX lost is Falcon 9 rocket on a launch pad due to dramatic explosion. During a routine preflight fueling test, the rocket and the $200 million Israeli Earth […]
A rolling bearing preferably runs under EHL conditions. The film thickness between the rolling elements and the rings is determined by the lubricant properties, operating conditions and bearing design. During the initial phase of operation, […]
Earlier this month, tribologists and physicists at the U.S. Department of Energy (DOE) Argonne National Laboratory published news of their (self-described) “self-healing diamond-like carbon coating [that] could revolutionize lubrication” in the journal Nature. The researchers […]
“God made the bulk; surfaces were invented by the devil”, a Nobel prize winning physicist Wolfgang Ernst Pauli said. In tribology, as in many other sciences, surface features (asperities, roughness) play an important role. In […]
Tiny particles are all over around us and sometimes they may create problems. This is especially of concern with metal particles formed due to wear in man-made engineering devices. Particles formed in car disk brakes […]
