Configure Power Source

Use the 'Configure Power Source' to make sure the 'driving' element is correct: a Joint, 2D-Cam, Gear-Pair, or Spring.


When you use Calculate Forces and Display Force-Vectors, MechDesigner puts a Power Source at the joint that has it motion specified by a Motion-Dimension FB. This is the default case.

However, especially with inverse-kinematics, that the input driving is not at the joint with the Motion-Dimension FB. Then, we must move the Power Source to a Joint, Spring or Cam.

Configure Power Source icon

[Right-side of Graphic-Area]: Forces toolbar > Configure Power Source

Menu:

Add menu > Forces sub-menu > Calculate-Forces FB

Dialog-box:

Configure Power Source dialog-box

What to do:

To open the Configure Power Source dialog-box

1.Click a kinematically-defined Chain [with the Icon-Solved-KinChain Symbol] in the Kinematics-Tree
2.Click Force toolbar > Configure Power Source

KT-ConfigurePowerSource

 

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

The orange square must show around the icon to the left of the Kinematic-Chain KT-Kinematic-Chain-Solved-Selected

2.Right-click the kinematic-chain or icon with the orange square
3.Click Configure Power Source in the drop-down menu [only one item in menu!]

Why use:

We use the Configure Power Source dialog-box to move the Power Source to a:

Different joint in the kinematic-chain - Pin-Joint or Slide-Joint

- or -

2D-Cam

- or -

Spring

Result:

MechDesigner opens the Configure Power Source dialog-box.
