Abstract:
The problem of mobility is a major challenge faced by the Hermiplegia, Mobility is essential in human daily activities as lack of mobility often results in boredomness and frustration, mostly affected are hermiplegia, hence the need to research into how the mobility challenges of these categories can be ameliorated. Most aged are faced with age induced ailment such as hermiplegia. In this research a hundred anthropometric data of the aged from within sixty years and above for both male and female hermiplegia were collected. The results were analysed to obtain their 5th, 50th and 95th percentile distributions. The analysed data was used to design the vehicle using Autodesk Inventor, a design parametric software. The vehicle was subjected to dynamic simulation and finite element analysis of the components parts. The vehicle is battery powered which comprises of component parts such as battery, electric motor, motor controller, frame and chassis. The transmission system, chassis, steering and braking system, suspension system were designed with appropriate design equations. The power requirements of the vehicle is 6 hp, finite element analysis on the vehicle chassis shows that the maximum von misses stress on the vehicle is 34.11 MPa is far less than the yield strength of mild steel of 207 MPa which means that the vehicle chassis will not fail due to stress while in operation. The vehicle design has a factor of safety 15. The vehicle is designed for ease of fabrication and maintenance.
