Move
Forced movement of a flange according to an angle, speed and angular acceleration signal
Library
Modelica/Mechanics/Rotational/Sources
Description
Flange flange is forced to move relative to flange support with a predefined motionaccording to the input signals:
u[1]: angle of flange u[2]: angular velocity of flange u[3]: angular acceleration of flange
The user has to guarantee that the input signals are consistent to each other,i.e., that u[2] is the derivative of u[1] and thatu[3] is the derivative of u[2]. There are, however,also applications where by purpose these conditions do not hold. For example,if only the position dependent terms of a mechanical system shall becalculated, one may provide angle = angle(t) and set the angular velocityand the angular acceleration to zero.
The input signals can be provided from one of the signal generatorblocks of the block library Modelica.Blocks.Sources.
