Dialog: Configure Power Source

Configure Power Source

To calculate forces correctly, you must Configure the Power Source(s) correctly.

Each degree-of-freedom in each kinematic-chain receives its Power from an element.

We use the Configure Power Source dialog-box to make sure each kinematic-chain receives its Power from the correct element(s).

Power-Source elements can be:

•Joints (Linear or Rotary Motor)

•2D-Cams

•Springs

Important Example

Use this dialog when you want to calculate the Contact-Force between a Cam-Roller and 2D-Cam. The default Power-Source is at the Joint at which you add the Motion-Dimension FB for that kinematic-chain. In packaging machinery, the motion-dimension is most often at the Tool-Part and not at the Cam-Follower Part . You must use this dialog to move the Power Source element from the Tool-Part to the 2D-Cam. Only then will you be able to calculate the Contact-Force, Contact-Stress AND the forces in all of the Joints in that kinematic-chain.

Even if the kinematic-chain is only the Cam-Follower Part, you must use this dialog to move the Power Source element from the Cam-Follower Part to the 2D-Cam to correctly calculate Contact-Force and Contact-Stress of the Cam.

Open Configure Power Source dialog-box

Configure-Power-Source in the Kinematics-Tree

Configure-Power-Source in the Kinematics-Tree

To open the Configure-Power-Source dialog-box:

1.Click a Kinematic-Chain that is kinematically-defined in the Kinematics-Tree

2.Right-Click the Kinematic-Chain

3.Click Configure Power SourceRed-14-2 in the pop-up menu

- or -

1.Click a kinematically-defined chain in the Kinematics-Tree

2.Press the ALT+P key combination on your keyboard

The Configure Power Source dialog-box is now open.

There are two tabs in the dialog-box:

Motion Dimensions

Red-14-1 Motion-Dimensions | Motor Element

The default Motor-Element for a Motion-Dimension is the Joint controlled by the Motion-Dimension.

Even if the default Motor Element is correct, please so these steps:

1.Click a Motion-DimensionRed-14-1

Before you do '2', below, make sure the Motion-Dimension is active.

Red-14-2 Motor Elements

The Motor Elements that can possibly drive the active Motion-DimensionRed-14-1 show in the box belowRed-14-2.

Each possible Motor ElementRed-14-2 is identified with a unique name and an icon.

2.Click a Motor ElementRed-14-2

When you click a Motor Element, it shows to the right of the Motion-DimensionRed-14-1

Note-Pencil-20 MD14+: If there is a Conjugate-Cam in your model, you must do Add Conjugate-Cam FB . Then, the Conjugate Cam element is also a Motor-Element.

If the kinematic-chain has two or more degrees-of-freedom - then you must choose the Motor Element for each Motion Dimension.

Dialog-13.2-ConPowSource-Colors

When you Show Force-Vectors, you can customize the Force-Vectors in the graphic-area.

For each Part, you can:

•Change the color of the Part-Outline and Force-Vector

•Display the Force-Vector:

a.from the Joint

b.as a Polygon of Forces

c.a and b

d.not a and not b

These options do not help me very much!
