Created using ANSYS 14.5. Tutorial instructions work with ANSYS 14.0 and 15.0. There are minor layout changes in ANSYS 15.0.
In this tutorial, you will learn to:
Determine the displacements and stresses in a bike crank using 3D FEA capabilities in ANSYS Mechanical
Verify the finite-element results from ANSYS by refining the mesh and also comparing with hand calculations
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 .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 Mechanical, determine the following:
Deformed shape and displacement field
Stress distribution
