Design and Static Tests of an All-Terrain Suspension System for Electric Wheelchair

The purpose of this article is to present the process of design and simulation, design, and testing of a Rocker-Bogie-like suspension system, for use in an all-terrain electric wheelchair. This suspension is a base of a six-wheel remote-controlled platform adapted to the rough-terrain conditions. The first stage of the designing process is to create a CAD model and perform the simulations for its configuration. After conducting analyses, the suspension model was made of plywood, MDF and 3D printed parts. This is the essential stage between CAD drownings and the aluminum model. The last step of the process of building Rocker-Bogie suspension is to make an aluminum structure and then conduct field tests under controlled conditions.
