Components.Rod

Rod without inertia.

A translational rod without inertia and two rigidly connected flanges. The rod transmits force without any mass effect:

$$0=flange\mathrm{\_}a.f+flange\mathrm{\_}b.f$$

The rod length L (inherited from PartialRigid) sets the fixed distance between flanges:

$$flange\mathrm{\_}b.s-flange\mathrm{\_}a.s=L$$

This component extends from TranslationalComponents.Interfaces.PartialRigid

Usage

TranslationalComponents.Components.Rod(L=0.0)

Parameters:

Name	Description	Units	Default value
L	Length of component, from left flange to right flange	m	0.0

Connectors

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

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

Variables

Name	Description	Units
s	Absolute position of center of component	m
