Abstract
The prosthetic socket is the key part connecting the prosthesis and the stump. It needs to be functional, safe, and comfortable at the same time. However, the volume fluctuation of the stump causes the incompatibility between the stump and the socket. This paper designs an adaptive prosthetic socket with rope-driven to fit stump volume fluctuation. The designed adaptive prosthetic socket with constant force characteristic using superelastic shape memory alloy may solve the problem of uneven pressure on the stump due to stump volume fluctuation and adapt stump volume. To obtain a good constant force range, the constant force characteristic of the socket is optimized and validated by finite element analysis. The experimental results show that the constant force mechanism using the C-shaped shape memory alloy sheets can obtain good constant force characteristics, and the socket can apply a constant force to the stump to solve the problem of uneven pressure distribution between the stump and the socket.
期刊介绍:
The aim of the International Journal of Applied Electromagnetics and Mechanics is to contribute to intersciences coupling applied electromagnetics, mechanics and materials. The journal also intends to stimulate the further development of current technology in industry. The main subjects covered by the journal are:
Physics and mechanics of electromagnetic materials and devices
Computational electromagnetics in materials and devices
Applications of electromagnetic fields and materials
The three interrelated key subjects – electromagnetics, mechanics and materials - include the following aspects: electromagnetic NDE, electromagnetic machines and devices, electromagnetic materials and structures, electromagnetic fluids, magnetoelastic effects and magnetosolid mechanics, magnetic levitations, electromagnetic propulsion, bioelectromagnetics, and inverse problems in electromagnetics.
The editorial policy is to combine information and experience from both the latest high technology fields and as well as the well-established technologies within applied electromagnetics.
