Comparing Two Feet

A project log for Mechanized Prosthetic Foot

The purpose of this project is to design and build a fully mechanized prosthetic foot that is more accessible than current solutions.

As with the last design this group did, one of the goals was to ensure that the structure under peak loading should have very uniform stress distributions, and that all parts should be subject to approximately the same stresses. The structure was therefore designed to reduce as much as possible any forces that are not axial to structural members. This resulted in a design with well-understood weak points in the linkage bars near the ends.

The stresses measured in the simulation model closely matched the figures predicted using python (within 5%). This is an expected result because the figures created using python assume perfectly symmetrical loads, no deformation, and are strictly 2-dimensional in nature.
