Abstract:

Exoskeletons are devices developed for muscle rehabilitation and/or adaptation to the social life of people who lost their limbs for various reasons. In this study, a lower limb exoskeleton made of A Glass Fiber material has been designed by using the Solidworks program. Biomechanical analyses have been carried out during two gait cycles by superimposing the design model on the musculoskeletal system in the AnyBody program. As a result of these biomechanical analyses muscle activities, muscle force, joint moment, and reaction force data have been obtained. Data have been collected and analyzed on two different groups, exoskeleton, and non-exoskeleton. It has been observed that the A Glass Fiber material used in the design reduces the weight of the exoskeleton to approximately 8-9 kg including the engine weight. It has also been seen that the proposed structure reduces the force on muscles and joints more than similar exoskeletons designed in the literature. Moreover the simulation results have represented that the S-shaped structure of the femur and tibia is more suitable for the human body structure. Finally, it has been concluded that walking with an exoskeleton increases the psoas major muscle to work more and this increases the anterior-posterior strength of the hip.
