Modelling the dynamics of the force interaction between the prosthetic sleeve and the patient's hand

Abstract

The article deals with the design processes of modern prostheses of the upper limbs, including the prosthetic sleeve. It has been established that the applied design methods and manufacturing technologies for prosthetic sleeves do not take into account the elastic-rigidity characteristics of human hand tissues interacting with the prosthesis. The review made it possible to determine the existing problems in the field of creating prosthetic sleeves. The authors considered the issues of using data from the results of the experiment to reconstruct the forces that arise between the patient's stump and the cult-receiving sleeve. A feature of the work is the study of the results of the experiment modelling the dynamics of power loads. The findings allow us to supplement the Bio Sculptor patient stump analysis system. The nature of the force interactions of the prosthesis and the human hand in the process of performing movements is considered on the basis of a virtual model.
