3D Finite Element Analysis of a Bike Crank Using ANSYS AIM
Created using ANSYS 16.2. There may be some differences in newer version (AIM 17.0)
Learning Goals
In this tutorial, you will learn to:
- Determine the displacements and stresses in a bike crank using 3D FEA capabilities in ANSYS AIM
- Verify the finite-element results from ANSYS by refining the mesh and also comparing with hand calculations
- Gain a better understanding of the new ANSYS AIM software and its comparison to Workbench.

Problem Specification
Under Construction
Consider the following bike crank model:
To orient ourselves, the following figure shows the location of a similar bike crank mounted on a bicycle.
Material properties: The bicycle crank's material is aluminum 6061-t6. The Young's modulus is 10,000 ksi, and the Poisson's Ratio is 0.33 .
Boundary conditions: Apply a load of 100 lbf in the y-direction on the right hole surface and fix the 3 left hole surfaces as shown below. Note that this is an approximation of the actual loads and constraints on the bike crank.
Using ANSYS AIM, determine the following:
Deformed shape and displacement field
Stress distribution
