Sources.Accelerate

Forced movement of a flange according to an acceleration signal.

The input signal a_ref in [m/s²] moves the 1D translational flange with a predefined acceleration. The velocity and position of the flange are determined by integration:

$$\begin{gathered} v= \\ fracdsdt \end{gathered}$$$$\begin{gathered} a= \\ fracdvdt \end{gathered}$$$$a=a_{ref}$$

This component extends from TranslationalComponents.Interfaces.PartialElementaryOneFlangeAndSupport2

Usage

TranslationalComponents.Sources.Accelerate()

Connectors

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

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

• a_ref - This connector represents a real signal as an input to a component (RealInput)

Variables

Name	Description	Units
s	Distance between flange and support (= flange.s - support.s)	m
v	Velocity of flange with respect to support	m/s
a	Acceleration of flange with respect to support	m/s2
