Move

Forced movement of a flange according to a position, velocity and acceleration signal

Description

Flange flange_b is forced to move relative to the support connector with a predefined motionaccording to the input signals:

    u[1]: position of flange    u[2]: velocity of flange    u[3]: 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. 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 position = position(t) and set the velocityand the acceleration to zero.

The input signals can be provided from one of the signal generatorblocks of the block library Modelica.Blocks.Sources.
