Cinétique et énergétique de la propulsion en fauteuil roulant manuel

Abstract : The purpose of this thesis is to propose a computing method of the mechanical power produced by manual wheelchair (MWC) users during actual displacements. This method is based on a 3-D mechanical model involving the kinematics of the Subject's segments and the MWC elements, and the efforts exerted by the Subject on the MWC. The experimental validation of this model required the simultaneous use of a 3-D kinematic system and an instrumented wheelchair (WWE) allowing the measurement of the efforts applied by the Subject on the wheelchair seat and handrims during an actual straightforward displacement on a flat ground. The rolling resistance parameters were calculated as well as the power dissipated by these resistances. The kinetic power and the power of the weight of the {Subject + MWC} system were also computed then used for computing the internal mechanical power of the {Subject + MWC} system. The method presented in this thesis opens some interesting perspectives for the evaluation of MWC users' physical abilities, the optimisation of propulsion techniques and the improvement of public and private places accessibility.
