Abstract
The development of a new design of a leg prosthesis for interaction with inclined surfaces is of interest to provide a new level of comfort for people with disabilities. Based on the analogues and modern works in the prosthetics sphere, tree concepts of the prosthesis design are proposed. Spatial models of surfaces and solid models have been created. To confirm the operability of structures and determine the stress-strain state that occurs when interacting with a surface having a slope of 15° relative to the horizontal plane, the finite element method is used on spatial models of four variants of geometry. A comparative analysis of various variants of the prosthesis design under the same conditions is carried out. The results obtained showed that this design solution is workable, suitable for production and for 14.4% more efficient than standard designs with one slot in the spring element and 44.5% more efficient than designs without slots in the spring elements.
