Static structural analysis of wheel chair using a rocker bogie mechanism

Abstract Technology has developed to far greater heights than ever before resulting in many lives being dependent on them. One such case is the physically disabled people. The motion of physically disabled people who required support for moving on different terrains can be made independent with the help of a wheel chair using a rocker bogie mechanism. Rocker boogie mechanism is a suspension system that can climb obstacles having size twice the diameter of the wheel and also is less complicated compared to other suspension systems. Commercial finite element code, ANSYS is used to analyze the wheel chair using rocker bogie mechanism. Static structural analysis is performed and the parameters like hydrostatic pressure, total deformation, and normal stress is analyzed. The parameters are found to be within the acceptable limits and the design is found to be feasible.
