OBJECTIVES
Perform finite element analysis of a Bicycle Wrench using ANSYS Workbench.
Evaluate stress and deformation resulting from applied loads and constraints.
Evaluate that this design is satisfactory and will not fail during use.
INTRODUCTION
The Bicycle Wrench design intent is to simplify the model orientation of the wrench using FEA Analysis. To know what the best material for production of wrenches should be used.
Normal loading conditions were chosen to be 10N and 100N being applied to the wrench.
Analyzing these forces on the wrench is very beneficial when determining what material to use, and how much force that material will with stand.
ANALYSIS (Pre-Processing)
The part was modeled in Pro/Engineer and imported into ANSYS Workbench
All parts were assigned properties of Aluminum 6061 / Steel alloy construction
Factor of safety of 3 was applied on the part, telling us our tensile strengths, from which we could determine if the wrench would fail.
Fixed support was assigned at the left edge of the wrench
Design was statically analyzed
Conclusion - Advantages of Final Iteration
The cost difference of 6061 aluminum and structural steel can be seen below, which was used to calculate the cost per cubic foot of the material.
Our final analysis for this wrench is that if the consumer is looking for a lighter weight tool, the aluminum would be the best choice. If strength and cost are more important to the consumer than the structural steel would be the best choice.
