Rotary vane shock absorber, 1935. Lever arm shock absorbers were the first form of hydraulic shock absorber or damper used for car suspension.They appeared in the 1930s and were most commonly used in the 1950s and 1960s, but were replaced by telescopic shock absorbers in the 1970s. [1]
A less common type of dashpot is an eddy current damper, which uses a large magnet inside a tube constructed of a non-magnetic but conducting material (such as aluminium or copper). Like a common viscous damper, the eddy current damper produces a resistive force proportional to velocity. A common use of the eddy current damper is in balance scales.
A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction).
Motion Control encompasses every technology related to the movement of objects. It covers every motion system from micro-sized systems such as silicon-type micro induction actuators to micro-siml systems such as a space platform. But, these days, the focus of motion control is the special control technology of motion systems with electric ...
An active suspension is a type of automotive suspension that uses an onboard control system to control the vertical movement of the vehicle's wheels and axles relative to the chassis or vehicle frame, rather than the conventional passive suspension that relies solely on large springs to maintain static support and dampen the vertical wheel movements caused by the road surface.
A magnetorheological damper or magnetorheological shock absorber is a damper filled with magnetorheological fluid, which is controlled by a magnetic field, usually using an electromagnet. [1] [2] [3] This allows the damping characteristics of the shock absorber to be continuously controlled by varying the power of the electromagnet.
Rotary damper - rotary motion is dissipated as heat in a highly viscous fluid or gel. May use a smooth surface rotating cylinder and a smooth surface stationary interior wall with fluid/gel between. For more forceful motion absorption and higher surface area, a paddle wheel or toothed gear is used, with a similarly ribbed or studded stationary ...
MagneRide is an automotive adaptive suspension with magnetorheological damper system developed by the Delphi Automotive corporation, [1] [2] that uses magnetically controlled dampers, or shock absorbers, for a highly adaptive ride.
