Node

Node component

	Description
	The Node component models an ideal (zero radius) roller. An optional speed input sets the speed at which the Node component pulls the web, without slippage. Note: ${frame}_{a} [1]$ , ${frame}_{b} [1]$ , and ${frame}_{c}$ are at the same location.

	Usage
	The Node component must be between two Span components.

Connections

Name	Description	Modelica ID
${frame}_{a}$	Left web 3-D connection point	frame_a
${frame}_{b}$	Right web 3-D connection point	frame_b
${frame}_{c}$	Roller holder base frame; enabled when Use fixed base = false	frame_c
${web}_{a}$	Left (entry) web transfer information port	web_a
${web}_{b}$	Right (exit) web transfer information port	web_b
$v$	Real input signal for web speed [ $\frac{m}{s}$ ]	v

Parameters

Name	Default	Units	Description	Modelica ID
Use speed input	$false$		When checked (true), the speed input port is enabled	useSpeedInput
Velocity input unit	$\frac{m}{s}$		Select unit of velocity. Available when Use speed input = true	toUnitV
Use fixed base	$false$		When checked (true), frame_c is disabled and the roller frame is fixed in the inertial coordinate frame (additional position and orientation parameters are enabled instead)	useFixedBase
$r$	$[0, 0]$	$m$	Location of frame_b with respect to ground. Available when Use fixed base = true	InitPos
$θ$	$0$	$\deg$	Rotation about z-axis. Available when Use fixed base = true	InitAng
