| dc.description.abstract | The aim of this work is to develop a prosthetic hand with individual grip functionality on each finger, reproducing the natural movement of the hand. After the preparation of sketches and creating a virtual model, the final model shows dimensions: 124,04 mm × 246,57 mm × 38 mm (palm-covered) and an estimated weight of 1 kg, with all components. Afterwards was executed the functioning simulation of the prosthetic hand, elaborated prehension experiments were made using a metal cylinder, a rubber ball and a wooden pencil, with the tool Motion Study from Solidworks. However in the tests with the pencil was difficult to reach equilibrium, tells us that the hand is not functional with width smaller objects, because they require a bigger finger precision. Was made the study of forces applied in links thinner in different prehensions using the Finite Element Method. This study concluded that the aluminum alloy 2024 T3 has enough resistance to the stresses incurred for the grasping. Finally, was made an estimate cost of production for a single working prototype prosthetic hand. The result was 1325€. | por |
