Fixed

Constrains a translational flange to a fixed position.

This component represents a mechanical anchor or a fixed reference point within a 1D translational system. It rigidly sets the position of its single translational flange (flange) to a constant value specified by the parameter s0. The key behavior is defined by the simple algebraic constraint:

$$flange.s=s0$$

math

Usage

Fixed(s0=0.0)

Parameters:

Name	Description	Units	Default value
s0	Fixed offset position	m	0

Connectors

• flange - (Flange)

Behavior

$$\begin{array}{rl}\mathtt{flange}\mathtt{.}\mathtt{s}\left(t\right)& =\mathtt{s}\mathtt{0}\end{array}$$
