Course: 22.425 - Design Machine Elements
Instructor: Chris Niezrecki
Three students also worked on a Failure Analysis of a Prosthetic Knee. A single axle knee joint for an economical prosthetic leg was the subject for a static and dynamically loaded failure analysis. A prosthetic leg is a complicated mechanical machine of various components. From prior research performed by the capstone student group that originally designed the leg, the bracket for the knee joint was assessed as the component most susceptible to failure. Since a failure of the prosthetic leg could result in bodily harm to a human, the leg was created based on a safety factor of 4 incorporated into the design.
