Electronic stability control (ESC), also referred to as electronic stability program (ESP) or dynamic stability control (DSC), is a computerized technology [1][2] that improves a vehicle's stability by detecting and reducing loss of traction (skidding). [3] When ESC detects loss of steering control, it automatically applies the brakes to help ...
Symbol for ABS. ABS brakes on a BMW motorcycle. An anti-lock braking system (ABS) is a safety anti- skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. [1] ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and ...
Pendulum floor slip resistance tester. The ASTM E303-22 [1] (United States), BS EN 16165:2021, [2] BS EN 13036-4:2011 [3] (United Kingdom and many other European nations), AS 4663:2013 - Slip resistance of existing pedestrian surfaces, and AS 4586:2013 - Slip resistance classification of new pedestrian surface materials (Australia/New Zealand) slip resistance test standards define the pendulum ...
A Formula Student car performing a skidpad test. (2009) A skidpad or skidpan [1] is a circular area of flat pavement used for various tests of a car's handling. The most common skidpad use is testing lateral acceleration, measured in meters per second squared (m/s 2) or the scaled unit g-force. This usage has similarities to that of using a ...
The thermodynamic method is used for performance testing of pumps, flow meter calibration, system curve tests, and other applications. It is capable of achieving results with uncertainties of less than 1% in pump efficiency and less than 1.5% in flow [3] while being able to test piping configurations where other conventional pump testing ...
In hydrogeology, an aquifer test (or a pumping test) is conducted to evaluate an aquifer by "stimulating" the aquifer through constant pumping, and observing the aquifer's "response" (drawdown) in observation wells. Aquifer testing is a common tool that hydrogeologists use to characterize a system of aquifers, aquitards and flow system boundaries.
A hydrostatic test is a way in which pressure vessels such as pipelines, plumbing, gas cylinders, boilers and fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test ...
Road slipperiness. A surface friction tester, used to measure road slipperiness. Road slipperiness is a condition of low skid resistance due to insufficient road friction. It is a result of snow, ice, water, loose material and the texture of the road surface on the traction produced by the wheels of a vehicle. [1]
