Learning Goals 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 h2. Problem Specification Consider the following bike crank model. \\ \\ [!crank_geo.png|width=400!|^crank_geo.png]\\ \\ To orient ourselves, the following figure shows the location of a similar bike crank mounted on a bicycle. \\ \\ [!crank_on_bike.png|width=400!|^crank_on_bike.png]\\ \\ *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. \\ \\ [!crank_bcs.png|width=400!|^crank_bcs.png]\\ \\ Using ANSYS Mechanical, determine the following: * Deformed shape * Displacement field * Stress distribution {latex}$\sigma_x(x,y,z)${latex} \\ \\ [*Go to Step 1: Pre-Analysis & Start-Up*|Bike Crank - Pre-Analysis & Start-Up] [Go to all ANSYS Learning Modules|ANSYS Learning Modules]\\ \\ |
