Translational Damper

Linear 1D translational damper

Modelica Standard Library

	Description
	The Translational Damper (or Damper) component models a linear 1-D velocity-dependent translational damper.

	Equations
	$f = d v_{rel} = - f_{a} = f_{b}$ $s_{rel} = s_{b} - s_{a}$ $v_{rel} = {\overset{&period;}{s}}_{rel}$ $lossPower = f v_{rel}$

Variables

Name	Units	Description	Modelica ID
$f$	$N$	Forces between flanges	f
$f_{x}$	$N$	Force applied to ${flange}_{x}, x \in \{a, b\}$	flange_x.f
$s_{rel}$	$m$	Relative distance between flanges	s_rel
$s_{x}$	$m$	Absolute position of ${flange}_{x}, x \in \{a, b\}$	flange_x.s
$v_{rel}$	$\frac{m}{s}$	Relative velocity between flanges	v_rel
$lossPower$	$W$	Loss power leaving component via heatPort	lossPower

Connections

Name	Description	Modelica ID
${flange}_{a}$	Left flange of compliant 1-dim. translational component	flange_a
${flange}_{b}$	Right flange of compliant 1-dim. translational component	flange_b
$heatPort$	Optional heat port	heatPort
