PartialRigid

Models a massless, rigid connection of a defined length between two translational 1D flanges.

This partial component defines an ideal rigid bar of length L that connects two translational 1D mechanical flanges, flange_a and flange_b. The component's position is characterized by the absolute coordinate s of its center point. The positions of the flanges are then kinematically constrained relative to this center point and the length L. The key equations governing these positions are:

\[flange\_a.s = s - \frac{L}{2}\]

\[flange\_b.s = s + \frac{L}{2}\]

This also implies that the distance between the flanges is fixed:

\[flange\_b.s - flange\_a.s = L\]

As a partial component, it is intended to be used as a base for other, more complete components.

Usage

PartialRigid(L=0.0)

Parameters:

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)
