Розрахунок статичної міцності рами протеза верхньої кінцівки людини

The research presents strength calculations for a human upper limb prosthesis made of polyamide PA 12, using the finite element method (FEM). A three-dimensional geometric model of the prosthesis was created for the calculations, exported and imported into the ANSYS software. The analysis was performed under nonlinear conditions, with the applied force ranging from 0 to 1500 N. The strength evaluation was carried out by comparing allowable stresses and deformations. The analysis presented in the study was conducted using a simplified model that does not account for the fasteners to the human limb. Based on the results, ranges of static loads in both horizontal and vertical directions were determined, within which the prosthesis does not fail.
