Reynolds equation is a partial differential equation that describes the flow of a fluid (typically lubricant) in the elastohydrodynamic or hydrodynamic contact. It is one of the main equations in the elastohydrodynamic (and hydrodynamic) theory […]
Fuel Efficiency It is essential to enhance the fuel efficiency of all machines to mitigate emissions and reduce energy consumption. Automobiles and machinery rely on lubricants for optimum operation and efficient energy transfer. In all mechanical systems, lubrication […]
Hydrostatic bearings are a particular type of bearings that work on the principle of separating sliding surfaces using pressurized fluid: air, oil or any other type of lubricant. This is in contrast with hydrodynamic bearings, […]
What is a friction brake? A brake refers to a device that primarily plays the role of slowing down or bringing to a halt an object in motion such as a vehicle, a bike, train, […]
What is a friction test? In tribology, measurement of friction consists of the evaluation of forces that occur and oppose a relative motion in a tribological contact. According to ASTM standard G 40, the friction […]
What is tire friction? The wheel is an ingenious invention that made a huge impact on our lives. The main achievement here is the reduction of friction of the rolling wheel against the road as […]
Meso scale air journal bearings are widely use in miniaturized rotary systems such as hard disk drives, laser scanners, micro motors, miniature precision machines, dentist drills, meso scale gas turbines, etc. In these systems the […]
What is Stribeck Curve? Stribeck curve is a fundamental and one of the most widely known concepts in tribology and lubrication fields. The concept represents the friction behavior in lubricated contacts as a function of […]
