To link a Motion to a Motion-Part in MechDesigner

Linking a Motion to a Motion-Part

Motions are defined with mathematical functions. You do not need to know the mathematics. The functions are displayed as graphs in MotionDesigner.

To make a Part in MechDesigner move with a Motion that is in MotionDesigner, we must link the motion to a Motion FB that is in the MechDesigner model.

The motion-values at the input-connector of a Motion FB become the X–axis values of the motion-graph.

The motion-values at the output-connector of a Motion FB become the Y–axis values of the motion-graph.

In the MechDesigner model, we connect the Motion FB to other FBs with wires to give the motion-values to a Motion-Part or Motion-Point, and so the model moves.

Add more Motion name-tabs in MotionDesigner.

When you start MechDesigner, there is one motion in MotionDesigner. The motion name is Motion0.

Usually, you will need to design more than one motion.

IN MOTIONDESIGNER

STEP 1: Add new Motion tabs

1.Click MotionDesigner to make MotionDesigner active

2.Click File toolbar > Add Motion

Do STEP 2 again, to add more motions

The default motion-names, after Motion0, become Motion1, Motion2...

STEP 2: Rename the Motions

It is easy to rename each motion:

1.Click a Motion name-tab to make the motion active

2.Right-Click the Motion name-tab

The Rename Motion dialog-box opens

3.Enter a New Name

4.Click OK

How to Link a Motion to a Motion-FB

Link a motion to a Motion FB that you add to the MechDesigner model.

IN MECHDESIGNER

STEP 1: Add a Motion FB to the graphic-area

1.Click Kinematic-FB toolbar > Motion FB

2.Click the graphic-area.

The Motion FB is now in the graphic area


In the default case, the Motion FB links to the left-most Motion name-tab in MotionDesigner.

To link the Motion FB to a different motion, edit the Motion FB.


STEP 2: Open the Motion FB dialog-box

1.Double-click the Motion FB in the main graphic-area, or Assembly-Tree

The Motion FB dialog-box is now open.

STEP 3: In the open dialog, select a Motion-name for the motion

1.Click the down-arrow of the Select Motion list-box

2.Click a Motion name in the drop-down list

STEP 4: Close the Motion FB dialog-box

1.Click GST-OK-11-15 at the top of the dialog-box
