Abstract

This research aims to analyze the performance of multi-purpose wheelchair structures using the finite element method (FEA) and analytical calculations. A wheelchair model was built and analyzed using FEA software to obtain stress, displacement and bending stress distributions. The FEA results show a maximum stress value of 415 MPa, a maximum displacement of 46 mm, and a maximum bending stress of 407 MPa, exceeding the mechanical properties limit of 6061 aluminum material. The analytical results produce a stress value of 57 MPa in the front structure, while the FEA produces a value of 46 MPa. The difference in results between these two methods can be caused by several factors, such as the assumptions used in analytical calculations and the geometric complexity of the FEA model. The conclusion we can draw from this research is that the design/structure of the multi-purpose wheelchair has exceeded the mechanical property values of the Aluminum 6061 material, which can cause structural failure in the components when fabricated.
