Abstract
The structure of racing wheelchairs has undergone several changes since the introduction of the modality in the paralympic games. These changes have brought about extraordinary improvements in athletes’ performance. Thus, the objective of this work was to evaluate the mechanical resistance of a new structural profile that can be applied in a race wheelchair. Two models of racing wheelchair with the same dimensions, but different structural profiles were designed. In one model, commercial commom structural profiles were used and in the other model an approximately triangular shaped profile was used. The models were computationally analyzed by the finite element method (FEM). The results of the analyzes showed that the triangular profile are better than commercial profiles in mechanical resistance and weight saving. Thus, the use of the new profile in the design of race wheelchairs is suggested, since it allows gain in performance, due to the decrease of weight.
