Design and Animation-Based Simulation of a Mechanical Prosthetic Limb

The paper presents the design and virtual simulation of a mechanical lower-limb prosthesis developed using three-dimensional modeling tools. The study focuses on the geometric construction of the prosthetic components and on the realization of animation sequences in order to simulate the flexion and extension of the knee joint. A digital prototype was created and assembled in a CAD environment, followed by the definition of motion constraints that reproduce the real mechanical behavior of the prosthetic joint. The animation allowed the observation of angular displacement, alignment between components, and possible interference during movement. The results highlight the usefulness of virtual simulation in validating prosthetic motion before physical fabrication.
