Abstract: The wheelchair is the primary rehabilitation device used to enable the movement capability of disabled people. To provide an appropriate wheelchair, the doctor will suggest the necessary customization has to be made on the existing one. However, the customization of a manual wheelchair is easy and cost-effective compared with the powered wheelchair due to simple structure and spare parts availability in the market... Because of the above, a novel concept is proposed. The rear wheels of the manual wheelchair are replaced with a Direct drive motor alloy wheel. CATIA – V5 is utilized to design the proposed wheel and ANSYS software is used to check its performance at different load conditions. The stress-bearing capability of different materials for various Direct drive motor weights is observed through structural analysis. The natural mode frequencies are found using modal analysis and its nature of vibrations is verified. The harmonic response analysis is used to test the nature of deformation and stress concerning natural frequencies for the applied force.
