Abstract
The Multifunctional Wheelchair is an automatic vehicle which reduces the user’s efforts and time while moving from one place to another. A wheelchair is a backbone of a disable person and it must be strong enough to sustain the loading of humans. So in present study a motorised wheelchair was designed in Catia and analysed by Ansys on the basis of vibration frequency. Two different materials were analyzed for result comparison to find out the best suited material, which can sustain the failure under vibration and external loading. From the result it was found that aluminium T6 6061 material has higher resonance frequency than Stainless steel- 304. Furthermore aluminium T6 6061 material made base frame was analyzed by static structural analysis with 80 kg of person load. The Simulation result shows that the design wheelchair can sustain the applied loading, because the value of maximum stress in base frame was less than yield strength of used aluminium T6 6061 material.
