SpeedSensor

Ideal sensor that measures the absolute translational velocity of a mechanical flange.

This sensor provides the absolute velocity of its connected flange. The velocity v is determined by taking the time derivative of the flange's absolute position s. The governing equation is:

$$v=\frac{dflange.s}{dt}$$

This component extends from PartialAbsoluteSensor

Usage

SpeedSensor()

Connectors

• flange - (Flange)

• v - This connector represents a real signal as an output from a component (RealOutput)

Behavior

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