Testing And Analysis Of Low Cost Prosthetic Feet, Morgan Carpenter, Carolyn Hunter, Dean Rheaume Apr 2008

Testing And Analysis Of Low Cost Prosthetic Feet, Morgan Carpenter, Carolyn Hunter, Dean Rheaume

Assistive Technology Resource Center Projects

The Center for International Rehabilitation (CIR) is a non-profit organization working in developing countries to rehabilitate those who have lost their mobility after an amputation. CIR has developed a lower limb prosthetic (monolimb) for transtibial amputees, which is then rigidly attached to a prosthetic foot. CIR requested a study of the effect of coupling their monolimb with two existing prosthetic foot designs; the International Committee of the Red Cross’s SACH foot and Northwestern’s Shape and Roll (SR) prosthetic foot. The combination of the prosthetic feet and monolimb were modeled and studied using finite element analysis (FEA). The FEA ...


Analysis Of A Lower Limb Prosthesis, Victoria Richardson, Erin Vozzola Apr 2008

Analysis Of A Lower Limb Prosthesis, Victoria Richardson, Erin Vozzola

Assistive Technology Resource Center Projects

The Center for International Rehabilitation (CIR) has programs all over the world to provide people in developing countries with the training and equipment they need to supply prosthetic devices to local landmine victims. CIR has created a monolimb, which is a lower limb prosthesis where the socket and shank are molded from a single piece of thermoplastic material. The monolimb can be fabricated on-site with minimal equipment at a low-cost. The shank portion of the device, which replaces the tibial region of the leg, was investigated through a finite element analysis computer program, COSMOSWorks. The current prosthetic device utilized by ...


Parametric Optimization Design System For A Fluid Domain Assembly, Matthew Jackson Fisher Apr 2008

Parametric Optimization Design System For A Fluid Domain Assembly, Matthew Jackson Fisher

Theses and Dissertations

Automated solid modeling, integrated with computational fluid dynamics (CFD) and optimization of a 3D jet turbine engine has never been accomplished. This is due mainly to the computational power required, and the lack of associative parametric modeling tools and techniques necessary to adjust and optimize the design. As an example, the fluid domain of a simple household fan with three blades may contain 500,000 elements per blade passage. Therefore, a complete turbine engine that includes many stages, with sets of thirty or more blades each, will have hundreds of millions of elements. The fluid domains associated with each blade ...
