Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Flange flange_b is forced to move relative to the support connector with a predefined motion according 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 that u[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 be calculated, one may provide position = position(t) and set the velocity and the acceleration to zero.

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