Description

The Sinusoidal Force Source block produces sinusoidal force with a constant offset. A positive force value generates force acting from port B to port F.

The defining equation for the sinusoidal force that the block generates is

$$F=F_o+A*\sin (2\pi ft+\phi ),$$

where:

• F is the output force.

• F_o is the offset force of the output.

• A is the peak amplitude of the sinusoid.

• f is frequency of the sinusoid in Hz.

• t is time.

• φ is phase shift of the sinusoid.

Parameters

Offset — Output average value

0 N (default)

Average value that the output sinusoidal force oscillates about.

Programmatic Use

Parameter: offset

Sinusoid peak amplitude — Output peak amplitude

1 N (default)

Peak amplitude of the output sinusoidal force.

Programmatic Use

Parameter: amplitude

Phase shift — Output phase shift

0 deg (default)

Phase shift of the output sinusoidal force.

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"sdl_lib/Sources/Sinusoidal Force Source"

Example: add_block("sdl_lib/Sources/Sinusoidal Force Source","myModel/myBlock",MakeNameUnique="on")

For information about programmatic access to individual block parameters, see the Programmatic Use section of parameter descriptions on this page.
