Parametric Modeling II Project #9
Objective: The student will use the Inventor Contact Solver to detect and resolve collisions among parts in conjunction with the Drive Constraint tool.
Assignment: Copy the following files to your working disk: GENEVA-BASE, GENEVA-DRIVER, GENEVA-WHEEL, and GENEVA-PIN.
Construct an assembly model of the GENEVA CAM ASSEMBLY.
Select the PLACE COMPONENT command and place the GENEVA-BASE part.
Select the PLACE COMPONENT command and place the GENEVA-WHEEL part.
Select the CONSTRAIN command and in the Place Constraint dialog box select the Mate constraint. Select the top horizontal surface of the GENEVA-BASE part as the first part for the Mate alignment command. Select the bottom face of the GENEVA-WHEEL as the second part selection to apply the Mate constraint.
Apply a second Mate constraint to align the axes of the cylindrical features. Move the cursor near the cylindrical surface of the center hole of the GENEVA-WHEEL and select the axis when it is displayed. Move the cursor near the cylindrical surface of the hole on the GENEVA-BASE and select the axis when it is displayed. In the Place Constraint dialog box, set the offset distance to 0.0 and click on the Apply button to accept the selection.
Place the remaining parts of the GENEVA CAM ASSEMBLY into the graphics window.
Constrain the remaining parts of the GENEVA CAM ASSEMBLY using the Insert constraint.
Add an Angle constraint to constrain the Driver.
Turn on the two datum planes that run the length direction of the GENEVA-BASE and the GENEVA- DRIVER parts.
Drag and rotate the GENEVA-DRIVER part to that an angle exists between the two parts. In the assembly panel select the Constrain command and in the Place Constraint dialog box select the Angle constraint.
Select the two datum planes and adjust the angle to 45 degrees. Select the Apply button to accept the selection.
Using the Inventor Contact Solver
In the Model History Tree window right-mouse-click on the Angle constraint of the GENEVA-DRIVER part to bring up the option menu and select Drive Constraint.
Click on the Expand option to reveal more control options. Switch off the Collision Detection option by clicking on the option box and removing the check mark. Click the OK button to close the message box.
Select Activate Contact Solver through the Inspect tab in the ribbon toolbars.

Using the Inventor Contact Solver (continued)
In the Model History Tree right-mouse-click on the GENEVA-WHEEL part to bring up the option menu and select the Contact Set option.
In the Model History Tree right-mouse-click on the GENEVA-PIN part to bring up the option menu and select the Contact Set option.
In the Model History Tree window right-mouse-click on the Angle constraint of the GENEVA-DRIVER part to bring up the option menu and select Drive Constraint. Click the Forward button to start the driver motion. Adjust the End angle as needed.
Create a motion simulation and record the simulation in standard Windows AVI file format.
Drawings:
Prepare a size “B” drawing paper and add the CCAC title block.
Add a standard orthographic assembly with a minimum of two views (Top view and Front view).
Display the views showing all hidden lines.
Add all centerlines for circles and cylinders only.
Add identification balloons to identify the part number of each part in the assembly.
Add a Parts List to the drawing.
Learner Outcomes Create an assembly model Constrain Inventor parts using the Mate, Angle, and Insert constraints Animate an assembly model using the Drive Constraint Tool Use the Inventor Contact Solver to detect contact between assembly components Create a fully annotated assembly drawing including center lines, identification balloons, and parts list
Evaluation: Refer to the PROJECT EVALUATION handout for the required items to be turned in for evaluation.
