Rotational Accelerate

Forced movement of a flange according to an acceleration signal

Modelica Standard Library

	Description
	The Rotational Accelerate (or Accelerate) component generates a forced rotational acceleration proportional to an input signal. The Use Support Flange boolean parameter enables a support flange on the housing. When true (checked) the support flange must be connected in the drawing. When false the component is internally fixed to ground.

	Equations
	$a = a_{ref} = \overset{&period;}{w}$ $φ = φ_{flange} - φ_{support}$ $w = \overset{&period;}{φ}$ $if Use Support Flange then τ_{support} = - τ$ $φ = φ_{flange} - {\begin{array}{c} φ_{support} & Use Support \\ 0 & otherwise \end{array}$

Variables
