Force-Data FB

To use the Force-Data FB correctly, do:

STEP 2: Add the Force-Data FB to the graphic-area - see Add Point-Data FB

STEP 3: Open the Force-Data Dialog-box to select a kinematic-element.

STEP 4: Select which Point in the kinematic-element - equivalent to Action and Reaction Forces.

The force-data at the Force-Data FB output-connector is the force that acts on the kinematic-element through the Point.

If the kinematic-element is a Power-Source, the force-data is the Load Torque to balance the kinematic-chain.

STEP 5: Connect a wire from its output-connector to plot the Force-Data over a complete machine-cycle.

Open the Force-Data dialog-box:

1.Double-click the Force-Data FB in the graphic-area.

- or -

The Force-Data dialog-box is now open.

Selection

STEP 1.Select a Joint, Cam, Gear, Rack, Ball-screw or Spring. You can click the element in the graphic-area or the Assembly-Tree.

When you select an element:

•The element shows in the box

•A list of Available Points shows in the box below, each with a 'Point Owner'

If you select a:

•Pin-Joint - there are 2 Available Points
Each Point that makes the Pin-Joint.

•Slide-Joint - there are 4 Available Points
Two Points on each Line that make the Slide-Joint.

•2D-Cam - there are 0 Available Points
The contact point is assumed.

•Spring FB - there are 2 Available Points
The Point that anchors each end of the Spring FB.

STEP 2.Click a Point in the box of Available Points, even if a Point shows in the 'Selected Force Output Element
