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.

Classical constitutive modeling is the diverse combination of springs and dashpots [12-16], for example, the Maxwell (M) and Kelvin (K) models, Burger model, generalized Maxwell model (GMM), and other models [17, 18].
The spring represents the elastic solid-like behavior where Hooke's law is valid (F = E[epsilon] where F is load or force, E is elastic modulus and [epsilon] is strain), whereas the dashpot represents the time-dependent, viscous liquid-like behavior where Newton's law is valid (F = [eta](d[epsilon]/dt) where [eta] is the viscosity or damping constant).
The tailhook dashpot puts positive pressure on the hook to keep it from skipping over the wires on touchdown and had been drained for the up-lock change.
Knoop's early apparatus was commercialized in 1940 but a dashpot was soon added to slow the indenter (5).
Such a model has many Maxwell elements (spring and dashpot in series) in parallel.

The changes of pressure in the resin and the compression stress taken from the reinforcement stack have been modeled using a simple Kelvin-Voigt model, considering a spring and a dashpot in parallel.

In this most simplistic model, a sensor is considered as a mass (m) connected to a Voigt model (a spring (k) and a dashpot (n) in parallel connection).
