Structural analysis of wheelchair lift system for express buses

Abstract

: As society ages rapidly, the number of wheelchair users is continually increasing. For this reason, public transportation systems should be improved in terms of disabled access. It is essential to develop an express bus for long-distance travel for wheelchair users. To institute an express bus for wheelchair users, it is necessary to design special entrance and lift systems. This study sought to develop a wheelchair lift system for express buses, and design a wheelchair lift system for express buses by evaluating structural integrity using the finite element model. For the analytical evaluation, the strength analysis for standard and endurance load conditions were performed using FMVSS Part 571.403. In case of standard load, it was evaluated that the lift system ensures against the guaranteed load. It is expected that the result of this study will be utilized in fostering the development of welfare services for the disabled.
