Abstract

A methodology for the design of Paralympics wheelchair wheels has been developed and provided a framework for comparison between design solutions. Finite element analysis was used as a tool to develop an understanding of wheel design, provide a basis for evaluation of design solutions, and as a mean of design optimisation. A finite element model of an existing wheel design was created and analysed. It was found that the pushrim was significantly over designed for the application. As such, wheel improvement focused on redesign of this component. A number of design solutions were analysed and compared based on weight, rotational moment of inertia, side profile surface area, and wheel stiffness. From this, it was decided that a thin pushrim attached via spokes to the rim and the hub in a tangential spoking pattern would offer the best solution.
