Abstract

This report contains all the necessary infonnation gathered from literature review and other technical sources to carry out this project. The aim of this project is to study, design and analyse H2 Gas Actuated Pneumatic Artificial Muscle (PAM) using Metal Hydride as the hydrogen storage medium. Studies and design on this project is intended to assist disabled and paralysed people physically. This project portrays an actuation system to idealise a more flexible mechanical system, which has longer serving-life, ability to deliver high force-to-weight ratio, and less mechanical wear compared to pneumatic piston cylinder actuator. The research discusses the ability, type, and quantity of metal hydride to store and release hydrogen to actuate the PAM. It also discusses the maximum amount of hydrogen gas that is needed for the actuation and hydrogen storage for 30mm diameter of BP AM. The validity of this actuation in the aspect of contraction/expansion is modeled with Finite Element ANSYS simulation for 3 diameters that are OD= IOmm, 20mm and 30mm. Design of functional prototype of prosthesis arm is shown with Catia V5RI2 3D modeling. This paper defmes PAM with a diameter of 30mm and length of 140mm is capable to produce 10.20% contraction with only 1.2g of sodium aluminium hydride. It gives 10.20% axial contraction i.e. from 140mm to 125.7lmm that is more than PAM with OD of lOmm and 20mm. v
