Rotational.ConstantTorque

This component extends from PartialTorque

Usage

TranslatedComponents.Rotational.ConstantTorque(tau_constant)

Parameters:

Name	Description	Units	Default value
useSupport		–	false
tau_constant		N.m

Connectors

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

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

Variables

Name	Description	Units
phi_support		rad
phi		rad
w		rad/s
tau		N.m

Behavior

$$\begin{array}{rl}\mathtt{phi}\left(t\right)& =\mathtt{flange}\mathtt{.}\mathtt{phi}\left(t\right)-\mathtt{phi}\mathtt{\_}\mathtt{support}\left(t\right)\\ w\left(t\right)& =\frac{\mathrm{d}\mathtt{phi}\left(t\right)}{\mathrm{d}t}\\ \mathtt{tau}\left(t\right)& =-\mathtt{flange}\mathtt{.}\mathtt{tau}\left(t\right)\\ \mathtt{tau}\left(t\right)& =\mathtt{tau}\mathtt{\_}\mathtt{constant}\\ \mathtt{phi}\mathtt{\_}\mathtt{support}\left(t\right)& =0\end{array}$$
