Design and Analysis of A Multifunctional Wheelchair

Abstract

Based on existing designs of multifunctional wheelchairs, a new wheelchair designed with body posture adjustment function is proposed to satisfy the needs of the elderly and the disabled. This paper shows the overall design of the wheelchair and the establishment of its 3D model at first; then, the kinematics analysis of the wheelchair's backrest adjustment mechanism, and verifying the smoothness of its reclining process with establishing a virtual wheelchair prototype for motion simulation in ADAMS; finally, finite element analysis of key components of the wheelchair to make sure their requirements of structural strength.
