Force-Data FB

Why add a Force-Data FB?

See also: Force-Data FB dialog

Use a Force-Data FB to measure, over a machine-cycle, the force* that acts ON a Point at a Joint, Spring, 2D-Cam, Pulley, or Rack-Pinion.

Use a Graph FB to plot force over a machine-cycle.

* Force:

The term we use for Kinetostatic Force and Torque data.

Kinetostatic Forces are those that arise in parts and at joints that have mass and mass moment of inertia, when the parts move with a prescribed motion. The moving parts and machine frame are perfectly rigid, there is no backlash in the joints, and the pre-scribed motion is followed perfectly.

Force-elements include: Joint, 2D-Cam, Spring, Pulley, Rack-Pinion,

A list of Available Points shows in the box below.

B.Select a Point in the box of Available Points

Even if a Point shows in the Selected Force Output Element box:

1.Click a Point in the box below Available Points

If you select a:

•Pin-Joint - there are two(2) Available Points
One Point on each Part of the Pin-Joint

•Slide-Joint - there are four(4) Available Points
Two Points on each Line of the Slide-Joint

•2D-Cam - zero(0) Available Points
Contact Point is selected

•Spring FB - two(2) Available Points
The Spring's Anchor Points

•Rack-Pinion - two(2) Available Points
The Contact-Points between the Rack and Pinion

C.Complete the command

3.Click OK-tiny-11-15 to close the Force-Data FB
