Design and Finite Element Analysis of a Metastructured TPU Liner for Transfemoral Prostheses 1: Università degli Studi di Enna "KORE"; 2: RO.GA. S.p.a.,Italy Managing the pressures at the socket-residual limb interface represents one of the primary challenges in the design of transfemoral prostheses. Indeed, the physiological volumetric fluctuations of the tissues throughout the day induces an increase of them, resulting in patient discomfort. This work illus-trates the development and analysis of a TPU liner, starting from the investi-gation of a modified re-entrant meta-structure in order to improve the pres-sure distribution in the critical region. With this aim, finite element simula-tions were carried out to study the mechanical behavior of the liner under specific loading conditions. Results highlighted how the proposed configura-tion ensures a pseudo-constant pressure variation over the physiological range of limb volume changes. Overall, the developed solution represents an effective approach to enhancing the biomechanical performance of the inter-face component, with potential positive implications for the user’s quality life. | |
