Assembly Contact Workshop 5 (cont.): Apply the 410,000 N-mm2 torque (moment) load With Edge Select active, select the line at the end of the crank Right-click in Geometry window and click Insert Force In the Details View, click Magnitude and enter 2050 (410,000/200) ANSYS Workbench Environment Assembly Contact 13g-2 13g-1 13g-3 (cont.): Change the direction of the applied force Click Direction in the Details View Select the top surface of the crank Click on the direction arrows to flip the direction Click on Apply in the Details View Click on the +Z (the blue arrow) in the Triad to confirm the load direction ANSYS Workbench Environment Assembly Contact 13h-3 13h-1 13h-4 13h-2 13h-5 Set up the solution options: Click the Solution folder in the Outline Tree In the Details View, change the “Save ANSYS db” to Yes and change the “Solver Type” to Direct ANSYS Workbench Environment Assembly Contact 14b 14a The Solver Type default is for the program to choose the solver (PCG or SPARSE), based on the geometry of the part for 3D solids. The “thinner” the part, the better the SPARSE solver performs relative to the PCG solver. In our case, since we created a mesh with varying element sizes (small near the contact area, large in the other areas), the SPARSE solver will most likely perform better. In addition, the SPARSE solver handles contact with friction better that the PCG. Define solution results: On the Solution Toolbar, click Stress and then click Equivalent (von Mises) (applied to All Parts) Again, on the Solution Toolbar, click Stress and then click Equivalent (von Mises) In the Details View, click Geometry In the Named Selection Toolbar, select “braces” from the drop down and click Select Items in Group Click Apply in the Details View (applied to only two parts of the model) ANSYS Workbench Environment Assembly Contact 15a,b 15c 15d 15e (cont.): Click in the Geometry window to un-select “braces” On the Solution Toolbar, click Deformation and then click Total (
