Display motion in Rack and Pinion through Dynamic Simulation.

1. Create a ‘New Assembly’ and save it with the name ‘Rack and Pinion-Dynamic Simulation’.
2. Select Place component from the marking menu and place the Pinion in the Assembly.
3. Align the Pinion in correct position by using View Cube.
4. Select the Pinion in the design window, right click and deselect Grounded from the context menu.
5. Open the visibility of Z Axis of Assembly and Z Axis of Pinion from the Browser Bar.
6. Apply a Mate Constraint between Z Axis of Assembly and Z Axis of Pinion.
7. Place a Mate Constraint between Centre Point of Assembly and Centre Point of Pinion.
8. Place the Rack in the Assembly and align it properly with Pinion by using Rotate Component Tool.
9. Apply a Tangent Mate between Pitch Circle of Pinion and Pitch Line of Rack.
10. Activate Angle Constraint, First select XZ Plane of Assembly, Second select XZ Plane of Rack and in the Third select front face of Rack, and click OK.
11. Create a Work Plane in the assembly, coplanar with the base of Rack.
12. Convert this Work Plane to ‘Grounded’ in the Browser Bar.
13. Set the browser from Assembly View to Modeling View using the toggle at the top of the browser.
14. Select Angle:1 Constraint in the Browser under the Constraints folder and Suppress it from the context menu.
15. Open the visibility of YZ Plane of Pinion and Work Plane 7 of Rack; later apply a mate constraint between them.
16. Turn off the visibility of Work Planes to make the screen clear.
17. Right click the Mate:6 in the browser and select Supress from the context menu.
18. Activate the Motion constraint, in the Type area select Rotation-Translation, and afterwards select the Pitch Circle of Pinion then Pitch Line of Rack. Fill the value 4.725 inch in the Distance Input box and click OK.
19. Activate the Dynamic Simulation Tool from the Begin Panel of Environments Tab.
20. Select Insert Joint in the Marking menu.
21. Select ‘Rolling: Cylinder on Plane’ from the drop down menu of Insert Joint dialog box.
22. Select Rolling constraint option.
23. In the Insert Joint dialog box, select Pitch Line of Rack in ‘Plane’ option and select Pitch Circle of Pinion in ‘Cylinder’ option. Click Ok.
24. Select Revolution:1 joint in the Browser under the Standard Joints folder, right click and select Properties from the context menu.
25. Click dof 1 (R) tab and select Edit imposed motion button and check the Enable imposed motion option.
26. Click the arrow to expand the input choices, and click Constant Value.
27. Enter the value (-575) deg/s and click Ok.
28. In Simulation Player, fill the value 1000 in the Images field area.
29. Clear the screen by activating the Clean Screen command.
30. Click Run in the Simulation Player to display motion in Rack and Pinion.
