Abstract

The purpose of this study is to solve an attendant's daily propelling wheelchair behavior, which is based on propelling force and walking speed against loads, for design of wheelchairs and other carts to handle materials. To obtain the propelling behavior, we proposed the model of the attendant propelling the wheelchair, such as the attendant is a motor, and the wheelchair is a load. Along with the model, we carried out experiments to solve the propelling behavior. The experiments were carried out on the ground and on a new type of a treadmill, which can generate various resistant forces. As the result, the propelling force increased and the walking speed decreased gradually with increasing the resistant force. This change is mostly along on a line. We also define a mechanical power of the propelling behavior and calculated the power. It was about 50W on daily use. The power of the propelling wheelchair is very small, therefore the comfortable design of attendant's wheelchair must be done with the ability of attendant's propelling. Copyright © 2004 by ASME.
