This page covers follow-on exercises to the bike crank tutorial. In particular, it shows how to add a strain gage to the ANSYS model to predict the strain that would be measured by a gage mounted on the crank model.

Strain Gage Modeling

The following video shows how to add a surface to the crank model to find the average strain over the area covered by a strain gauge mounted on the crank. The video includes audio as do other videos on this page. Note that you have to make the following modifications to the procedure shown in the video:

Manually Connecting Crank Arm and Gage

The above video shows how to add a connection between the crank arm and the gage using Create Automatic Connections. But this automated procedure doesn't always work. In that case, one has to connect the two entities manually using Insert > Manual Contact Region as shown in the video below.

Meshing with Hexahedrals using the Multi-Zone Method

The multi-zone method in ANSYS

The steps for using the multi-zone meshing method for the bike crank geometry are shown in the video below.

Creating a New Coordinate System in ANSYS Mechanical

If your default coordinate system is not centered on one of the holes in the crank, or you wish to learn how to define new coordinate systems inside the mechanical window, please refer to the following video:
