Redesign and Topological Optimization of Transtibial Prosthesis by Reverse Engineering
Presentation by Eduardo Bajo, FEA Engineer at IDAERO.
Presentation of a project consisting of redesign with topology optimization of a transtibial leg prosthesis. It is a project in which the reverse engineering workflow has been followed, starting with 3D digitization of an amputated limb and real old prosthesis. Subsequently, they have been reconstructed in 3D to simplify and applied topology optimization, taking into account the biomechanics of human gait, using Altair Inspire software. Finally, the reconstruction of the optimization through organic design has been carried out with the software Evolve.
This project won the 1st prize in the II International Industrial Design Contest UPM-Technical University of Madrid.
During the presentation it will be presented the new 2019 Edition of the Industrial Design Contest UPM, open to students and professionals, sponsored by Altair.
Leverage the Power of Simulation-Driven Design
In order to stay competitive while pushing the envelope on innovation, simulation must drive the entire design process from the early concept design phase all the way to production. Leveraging robust simulation—including motion analysis, finite element analysis, and manufacturing feasibility analysis—early and often has become a necessary driver to innovation and is helping numerous industry-leading companies to meet quality, cost, and time-to-market targets.
An Interview with Ben Farmer of Robot Bike Co. Discussing the Development of their R160 Bike with Altair
Robot Bike Company (RBC) is a new startup established in the UK by aerospace engineers and mountain biking enthusiasts who identified the potential of combining additive manufacturing technologies with carbon fiber to, in their own words, “create the best bike frames possible”. To deliver a customizable, lightweight, high strength bike, RBC’s frame was intended to be created from carbon fiber, a material very common in the industry. The carbon fiber tubes, as well as the bike’s other components and systems were to be joined by additively manufactured titanium ‘nodes’, manufactured based on the specification of individual riders. Altair ProductDesign’s engineering team was tasked with optimizing these joints, which included the head tube, seat post and chain stay lugs, to ensure they were as lightweight as possible and still able to withstand the forces of downhill mountain bike riding, all while being fit for the AM process.
