3. Assemble Exploded Model This tutorial shows how you can build a model in an exploded or unassembled form and automatically have it assemble before simulation. This can be useful if your model is complicated and has many small and closely connected parts.

4. What You Should Accomplish When you complete this tutorial you will have an exploded model that assembles and then runs a simulation.

5. Getting Started Getting Started: a. Under the heading "How would you like to proceed", select the Create a new model radio button. b. Choose a Location to save your files c. Set Model Name as assemble_exploded_model d. Verify the Gravity text field is set to Earth Normal (-Global Y). e. Verify that the Units text field is set to MKS - m,kg,N,s,deg. f. Select OK. a b c d e f

12. Create Box • Select Box from Rigid Body tool stack • Select Add to Part from Box pull down arrow • Turn on Length checkbox, enter (80.0cm)in the text field below • Turn on Height checkbox, enter (80.0cm) in the text field below • Turn on Depth checkbox, enter (20.0cm) in the text field below • Click PART_5 • Click (5.25, 3.1, 0) a f g b c d e

13. Modify Box Location • Right-click on box, select Marker: MARKER_24 Modify • Enter 5.25, 3.1, -0.1 in Location text field • Click OK b a c

14. Add Revolute Joint • Select Revolute joint from Joint stack • Select 1 Location from Construction pull down menu • Click on ground.MARKER_1 a b c

15. Create Revolute Joint • Create a revolute joint at ground.MARKER_5 a

16. Create 2 Body – 2 Location Revolute Joint • Click Revolute joint • Select 2 Bod-2 Loc from Construction pull down menu • Click PART_6  ground  marker 11  marker 12 a b c

17. Add Rotational Motion • Click Rotational Motion from Motion Driver tool stack • Enter (360d) in Speed text field • Click JOINT_1 a b c

18. Create 2 Body – 2 Location Spherical Joint • Select Spherical Joint from Joint tool stack • Select 2 Bod-2 Loc from Construction pull down menu • Click PART_2 PART_3 ground.MARKER_2 ground.MARKER_3 • Create a second 2 Bod – 2 Loc spherical joint: • PART_5 PART_6 ground.MARKER_9 ground.MARKER_10 d c a b

19. Create 2 Body – 2 Location Hooke Joint • Select Hooke Joint from Joint tool stack • Select 2 Bod-2 Loc from Construction pull down menu • Click PART_3  PART_4  ground.MARKER_4  ground.MARKER_6  cm (PART_3)  MARKER_17.X a c b

20. Create 2 Body – 2 Location Cylindrical Joint • Select Cylindrical Joint from joint tool stack • Select 2 Bod-2 Loc from Construction pull down menu • Click PART_4  PART_5  ground.MARKER_7  ground.MARKER_8  cm (PART_4)  MARKER_5 a b c

21. Verify Verify your model NOTE: ADAMS/Solver will display errors because the distance between the two parts is too far for a joint to exist.

22. Model This is what your screen should look like when your model is complete

23. Run Simulation • Click Simulation tool • Click button • Click Perform initial conditions solution tool • Select Step Size from pull down arrow, enter 0.01 • Click Play e a d c b

24. Topics Covered In this tutorial you will learn how to: • Create Marker • Create Link • Create Marker • Create Revolute joint between 2 Bodies and 2 Locations • Create Spherical joint between 2 Bodies and 2 Locations • Create Hooke joint between 2 Bodies and 2 Locations • Create Cylindrical joint between 2 Bodies and 2 Locations • Perform initial conditions solution

25. Best Practices • Make sure the units are correctly set. • Make sure the joints is in the correctdirection. • Check dimensions of your parts to make sure they are correct. • Check orientation of the parts and joints to make sure it is correct. • Make sure your model verification is successful • Make sure the measures are set properly. • Make sure the plot is displaying the correct set of results.
