Sources.ConstantSpeed

Constant speed, not dependent on force.

Model of fixed velocity of flange, not dependent on force. The velocity of the flange with respect to the support is fixed to the parameter v_fixed.

The equations are:

$$\begin{gathered} v= \\ fracdsdt \end{gathered}$$$$v=v_{fixed}$$

This component extends from TranslationalComponents.Interfaces.PartialForce

Usage

TranslationalComponents.Sources.ConstantSpeed(v_fixed)

Parameters:

Name	Description	Units	Default value
v_fixed	Fixed speed (if negative, force is acting as load)	m/s

Connectors

• flange - This connector represents a mechanical flange with position and force as the potential and flow variables, respectively. (Flange)

• support - This connector represents a mechanical flange with position and force as the potential and flow variables, respectively. (Flange)

Variables

Name	Description	Units
s	Distance between flange and support (= flange.s - support.s)	m
f	Accelerating force acting at flange (= flange.f)	N
v	Velocity of flange with respect to support (= der(s))	m/s
