dashpot

[′dash‚pät]
(mechanical engineering)
A device used to dampen and control a motion, in which an attached piston is loosely fitted to move slowly in a cylinder containing oil.

dashpot

A mechanical, hydraulic, or pneumatic damper used to cushion or slow down mechanical movement by restricting the flow of viscous fluid. Dashpots are used in shimmy dampers and in some power control systems, where they come into operation at high speeds to prevent pilot-induced oscillations. See dashpot throttle.

The SLS model consists of a spring in series with a dashpot and in parallel with another spring, resulting in three unknown parameters.
Knoop's early apparatus was commercialized in 1940 but a dashpot was soon added to slow the indenter (5).
In curve B, which is a single dashpot, stress and strain are related by the Newtonian equation:
The dashpots are assigned at the exterior nodes of the base row.
Considering obtained yield data from performed compression tests at different strain rates, component-specific curves are driven to measure parameters of viscoplastic dashpots.
Standard ZWT model is applied by combination usage of springs and dashpots, representing elastic and viscous factors separately.
Because, in general, a very broad range of relaxation times is spanned by a relaxation process, an appropriately large number of springs and dashpots, and therefore model parameters are required to accurately model properties over a wide time range.
The resistance of the spring elements is accounted for by the modulus (E) terms, and relaxation time ([tau]) accounts for the viscous response of the dashpots.
This analogical model is made by the association of springs and dashpots.
The Burgers model is a theoretical model that uses a combination of springs and dashpots connected in a series and parallel arrangement to describe the viscoelastic macroscopic behavior of materials (23).
The Burgers model is a combination of the Maxwell (springs and dashpots in series) and the Voigt (springs and dashpots in parallel) models connected in series.
