Design of the Hydraulic Cylinder Assembly of an Above-knee Prosthesis With the Objective of Mass Reduction
Year: 2024
Type: article
Abstract: The hydraulic cylinders used on the above-knee leg prosthesis must meet very precise geometric, functional and mass requirements. Such can only be found abroad, but procurement is complicated and prices are high. The topic of this paper is the analysis of the possibility of manufacturing and purchasing such cylinders on the domestic market, and the optimization of solutions obtained from domestic companies with the aim of reducing mass. In the paper, an analytical and numerical analysis of the minimum required wall thickness of the cylinder tube and the minimum thickness of the connecting rod was performed. At the end of the paper, an optimized solution with reduced mass by about 70% compared to the conceptual solution was given.
