Therefore, we can neglect the strain changes in the x-direction, and assume strain only varies in the y-direction. However, lucky for us, the strain does not vary much in the x-direction of the bike crank. We are trying to find the average of the strain over the entire area of the strain gauge.
#SOLUTION MENU ANSYS HOW TO#
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: When the parameters of the path have been set, right click on the path you just created in the project tree in the outline window and select Rename. Change the number of sampling points to 50. Creating a path in Workbench is very easy: you just have to specify the starting and ending points of your path and workbench will create it. This will open up the path toolbox in the details window. Next, go to Construction Geometry > Path. The next thing we are going to do is to set up a path where the strain gauge lies on the bike crank. Now, create another stress the same way, but change Orientation to Y Axis and rename it StressYY Construction Geometry In the details pane, ensure Orientation is set to X Axis, and Geometry is set to All Bodies.
In the solution sub menu, select Stress > Normal. We will also look at the stress of the bar to verify the simulation against the theory. Now in the solution sub menu click Deformation > Total to add the total deformation to the solution. To add deformation to the solution, first click to add the solution sub menu to menu bar. This will allow us to catch any obvious errors we have made setting up the simulation.

Verification & Validation Solution DeformationĪlthough we are only looking for the strain at the strain gauge location, we should also check the deformation of the crank to see if the solution makes intuitive sense. Author: Benjamin Mullen, Cornell Universityħ.
