Fixed

Represents a mechanical rotational element fixed at a specified angle.

This component models a shaft that is rigidly clamped or fixed in its housing, preventing any rotation. The angle of this fixed shaft, phi0, is a configurable parameter. It effectively acts as an angular boundary condition in a 1D rotational mechanical system. The core behavior is defined by the equation that sets the angle of its connection spline (spline.phi) to this fixed parameter phi0:

\[spline.phi = phi0\]

Usage

Fixed(phi0=0.0)

Parameters:

Connectors

• spline - This connector represents a rotational spline with angle and torque as the potential and flow variables, respectively. (Spline)

Behavior

\[ \begin{align} \mathtt{spline.phi}\left( t \right) &= \mathtt{phi0} \end{align} \]
