Numerical Modelling of Loads on the Structural Elements of an Innovative Mechanism Enabling Wheelchairs to Negotiate Stairs
Abstract:This article presents a numerical study of the loads on the structural components of an innovative system designed to enable a typical wheelchair to negotiate stairs. Such a system is a structure of several levers moved in an appropriate sequence. An important aspect of the design described was that it should not be a completely new wheelchair structure, but merely a set of mechanisms which, when fitted under the seat, would enable the user to negotiate stairs and other obstacles arising from the difference in… Show more
