Move
Forced movement of a flange according to an angle, speed and angular acceleration signal
Library
Mechanics/Rotational/Sources
Description
Flange flange is forced to move relative to flange support with a predefined motion according 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 that u[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 be calculated, one may provide angle = angle(t) and set the angular velocity and the angular acceleration to zero.
The input signals can be provided from one of the signal generator blocks of the block library Modelica.Blocks.Sources.
