What is a Slide-Joint?

MechDesigner definition: a Slide-Joint makes a Line in a Part become co-axial (coincident) with a Line in a different Part. The two Parts can slide relative to each other, along the coaxial Lines.

IFTOMM Kinematic definition: a Slide-Joint makes an axis in one part become collinear with an axis in a different part, but allows the axes to slide relative to each other.

IMPORTANT: To calculate reaction forces for a Slide-Joint:

The length and position of the Lines that define a Slide-Joint must be equivalent to the actual design.

GA-SlideJointDefined

Slide-Joint in the graphic-area:

Red-14-1b Narrow Rectangular Box - its length is equal to the length of Line '1' you select for the Slide-Joint

Red-14-2 Wide Rectangular Box - its length is equal to the length of Line '2' you select for the Slide-Joint

Red-14-3 Arrowhead to show the Positive-Direction* - is at the start-Point of one of the Lines you select for the Slide-Joint

* Positive-direction becomes important if you add a Motion-Dimension FB to the Slide-Joint.

STEP 1: Add Slide-Joint

Icon-AddSlideJoint

Add menu > Mechanism sub-menu > Add Slide-Joint

Kinematic Elements Toolbar > Add Slide-Joint icon

STEP 2: Click the two Lines:

1.Click a LineRed-14-1b in a Free-Part

2.Click a LineRed-14-2 in a different Part


If the Select-Elements dialog-box opens, you have clicked more than two Lines.

1.CTRL+Click the two Lines (in two different Parts) in the Select-Elements dialog box.

2.Click OK-tiny-13-17 to close the Select-Elements dialog-box

STEP 3: Complete the command

If the two Lines do not snap together:

1.Click the graphic-area

The two Lines become collinear.
