Tutorial by Rahul Singh Dhari
Small

Follow the steps to achieve slide curve motion.

  1. Step 1:

    Open the SlideCurve_without_kin.CATProduct document.

  2. Step 2:

    Select the Slide Curve Joint icon .The Joint Creation: Slide Curve dialog box is displayed

  3. Step 3:

    Click New Mechanism.The Mechanism Creation dialog box is displayed:
    In our example, keep the default name Mechanism.1.

  4. Step 4:

    Select Curve 1 either in the geometry area or in the specification tree. In our example, select the yellow sphere arc as shown below:

  5. Step 5:

    Select Curve 2 either in the geometry area or in the specification tree. In our example, select the line on the green part as shown below:

  6. Step 6:

    Click Ok to end the slide curve joint creation.

  7. Step 7:

    Now create a second joint (revolute joint) and a third joint (prismatic joint).

  8. Step 8:

    Revolute.2:
    select line .1 (right white lines)
    select line.2 (left white lines)

    select xy plane ( green) (plane 1)
    select xy plane (white lines) (plane2)

    Select the Angle driven check box in the Joint Creation Dialog Box

    when done click OK

  9. Step 9:

    Prismatic.3
    select line.1
    select line.2 as shown below:

    select xy plane (white lines) (plane 1)
    select xy plane (yellow sphere) (plane2)

    when done click OK

  10. Step 10:

    This is what you will obtain.

  11. Step 11:

    Click the Fixed Part icon in the Simulation toolbar or select Insert->Fixed Part... from the menu bar.

    Click the bottom cuboid for fixed part. (part 4)

  12. Step 12:

    The mechanism can be simulated.

    Double-click Mechanism.1 in the specification tree.

    The Kinematics Simulation - Mechanism 1 dialog box is automatically displayed.
