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 […]
Unbreakable: Water-Repellent Coating | MSE Anish Tuteja Anish Tuteja, Associate Professor of Materials Science and Engineering and Associate Professor of Macromolecular Science and Engineering, and his research group have created a self-healing, water-repellent spray-on coating […]
Under extreme conditions the lubricant film fails to separate the rubbing surfaces and solid-to-solid contact occurs. To prevent excessive wear of the base materials anti-wear additives are used in these cases. The additives create a […]
Wear in tribological contacts results in generation of wear particles of various sizes and shapes and these particles impact the performance of the mechanical devices. These particles may create additional mechanical damage or act as […]
The requirement for greater energy efficiency in engineering systems has led to a general reduction in lubricant viscosity, which means that an increasing number of engineering components operate under boundary lubrication conditions. As a result, […]
Controlling friction is one of the main goals in modern tribology. Due to complexity of the tribological processes, up to date the problem remains mainly unsolved. While classical tribology relies on the famous friction laws, […]
The classical lubrication theory suggests the use of oil to reduce wear by the development of a thin separating lubricating film. However, the trends in the industry dictate miniaturization of the mechanical devices with a […]
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 […]
