Modeling, analysis, and fabrication of load carrying equipment for elderly people

MECHANICAL ENGINEERING

Load carrying assistance is essential for elderly people at different places such as domiciles, hospitals, book shops, library etc. This paper aims to model, analyse, and fabricate load carrying equipment for elderly people with staircase climbing mechanism. Modeling of the equipment is completed using CATIA V5 R20. Maximum von Mises stress obtained for beam and frame is 35.6 MPa and 4.55 MPa respectively based on the analysis using CATIA V5 R20. Fabrication process involved several operations such as cutting, bending, drilling, grinding, welding etc. Machines used for these operations are laser cutting, drilling, grinding and welding. Total cost for completing the equipment is Rs. 13000. Post working analysis of equipment is satisfactory. In future, composite materials can be adopted in order to reduce overall weight of the equipment and rubber wheels can be employed to reduce vibration and to enhance smooth operation.
