- This tutorial uses the model created in the Piston CAD Model tutorial. If this tutorial was not completed use Meshed Piston.ach in your tutorial models folder.
- The joints between the piston and arm, and between the arm and crank, are trusses with a cross-sectional area of 1 in
2
.
- The joint at the free end of crank is made of round beam elements with a 0.5 inch radius.
- All CAD parts (bricks) are made of Aluminum 6061-T6; 6061-T651.
- All joint parts (trusses and beams) are made of Steel (AISI 4130).
- Apply a prescribed rotation to the joint at the free end of the crank that will go through one revolution in 1 second.
- Apply X, Y, and Z translational and Y and Z rotational constraints to the center of the joint at the free end of the crank.
- Apply X and Z translational constraints to the large cylindrical surfaces of the piston.
- Apply an X translational constraint to all surfaces of the crank.
- Specify an event capture rate of 36. This will produce results for every 10 degrees of crank rotation (360/36 = 10).
