Problem: Create the geometry of the Lift Mechanism and then set the contraints of the model and then simulate the model. Note: If you need assistance on a step, just click on it for more information. Note: Click on images to enlarge.

1) Click on New model.

2) Under Working Directory, browse to the folder where you want to save your model.

3) Type the name of the new Model name as lift_mech and click OK.

4) Make sure that the Gravity is set to Earth Normal (-Global Y) and the Units is set to MKS - m,kg,N,s,deg.

1) From the Settings menu, select Working Grid.

2) Set the Size in the X direction to 20 m and the Size in the Y direction to 20 m and the Spacing in the x and y direction to 0.5 m. Since the grid is in meters you will probably need to zoom out to see it.

3) Make sure that the working grid is oriented along the global XY direction (default setting when you open Adams/View). The Set Orientation pull-down menu allows you to choose Global XY, YZ, XZ, or custom orientation. Click Apply and OK.

1) Create the geometry of the lift mechanism based on the dimensions on the diagram above. For a challenge try to recreate the Lift Mechanism yourself and only use this guide if you are stuck. We're going to start with the Base first. Select the Rigid Body toolbox and select Box.

2) Then, under Length, enter 12 m, under Height, enter 4 m, under Depth, enter 8 m. Make sure all the Length, Height, and Depth boxes are checked.

3) Hit Enter and then right-click on the working grid to open the LocationEvent box, here enter 0,-4,0 and make sure Rel. To Origin is selected then click Apply.

1) Select the Rigid Body toolbox and select Box.

2) Then, under Length, enter 3 m, under Height, enter 3 m, under Depth, enter 3.5 m. Make sure all the Length, Height, and Depth boxes are checked.

3) Hit Enter and then right-click on the working grid to open the LocationEvent box, here enter 9,0,2.25 and make sure Rel. To Origin is selected then click Apply.

1) Select the Rigid Body toolbox and select Cylinder.

2) Then, under Length, enter 10 m, under Radius, enter 1 m. Make sure all the Length and Radius boxes are checked.

3) Hit Enter and then right-click on the working grid to open the LocationEvent box, here enter 0.5,1.5,4 and make sure Rel. To Origin is selected then click Apply.

4) Now click on the center of the Mount as shown to define the other endpoint of the cylinder.

1) Select the Rigid Body toolbox and select Cylinder.

2) Then, under Length, enter 13 m, under Radius, enter 0.5 m. Make sure all the Length and Radius boxes are checked.

3) Hit Enter and then right-click on the working grid to open the LocationEvent box, here enter -4.5,1.5,4 and make sure Rel. To Origin is selected then click Apply.

4) Now click on the center of either the Shoulder or the Mount as shown to define the other endpoint of the cylinder.

1) Select the Rigid Body toolbox and select Box.

2) Then, under Length, enter 4.5 m, under Height, enter 3 m, under Depth, enter 4 m. Make sure all the Length, Height, and Depth boxes are checked.

3) Hit Enter and then right-click on the working grid to open the LocationEvent box, here enter -6.75,1.5,2 and make sure Rel. To Origin is selected then click Apply.

1) From the Rigid Body toolbox select the Fillet tool.

2) Under Radius, enter 1.5 m, and then check the box for End Radius and enter 1.5 m.

3) Then select the edges of the Mount as shown and then right-click on it to create the fillets. You may want to rotate the view to make this task easier.

1) From the Rigid Body toolbox select the Chamfer tool.

2) Under Width, enter 1.5 m.

3) Then select the edges of the Bucket as shown and then right-click on it to chamfer it. You may want to rotate the view to make this task easier.

4) Now under the Rigid Body toolbox, select the Hollow tool.

5) Under Thickness, enter 0.25 m and make sure Inside is checked.

6) Then select the top face of the bucket and then right-click to hollow it out. You may want to rotate the view to make this task easier.

• Your final model should look something like this (Colors may vary.)
