The aim of this thesis is to introduce new designs for an upper-limb prosthetic socket and test rig which can assess any upper prosthetic socket while trying to simulate common arm movements in Euler angles (Yaw, Pitch, and Roll). The common arm movements during activities of daily living are (Abduction, Adduction, Flexion, Extension, Supination and Pronation). The assessed conventional socket was selected from Ottobock. The designs of socket and test rig were drawn by SolidWorks CAD software. The test rig has abilities to tilt at any plane to simulate the common arm movement and it can predict when the dislocation between the socket and residual limb will happen at any weight and plane. A live-lift and axial load tests were done by the test rig in Euler angles. The test rig has an advantage of introducing facility to assess prosthetic sockets without needing amputees to assess on them at first where that are common generally. So, it is important to find a material which can mimic soft tissues of human arm and has the mechanical properties that are close to mechanical properties of soft tissues. This study introduced two designs for prosthetic socket (Elliptical Spring socket and Mustard prosthetic socket) which can overcome problems of rejection among upper-limb amputees. The problems are such as humid environment, forces occurring inside the prosthetic socket due to the long time over load, and change in the weight of amputee and therefore change in volume of the residual limb’s circumference. The first design is inspired from structure of the spring to be adequate for many ranges of amputations. The second design is inspired from morphology of the mustard flower’s petal to allow more adaption with change in residual limb volume. Referring to the experimental work of the conventional socket Ottobock on mannequin’s arm without using paraffin wax, it was found that the live-lift force is larger than the axial-load force in all cases. Prototypes of the sockets were 3D printed from PLA material. In static assessment, results showed that Conventional socket PLA can endure the largest force among other sockets in live-lift and axial-load test. By using MATLAB software, Displacement-Time graph for free and forced vibration cases of new prosthetic sockets was shown. The results showed that the damping ratio of conventional socket PLA is the largest among other sockets.
