차량 좌석 대용 휠체어의 강도 시험법에 관한 연구 = A Study of Test Method for and Evaluation of Wheelchair Seating System

다국어 초록 (Multilingual Abstract)

As the number of wheelchair users increases, the safety of the wheelchair user is becoming a big concern. An increasing number of wheelchair users use their wheelchairs as motor vehicle seats when traveling. A standard requires that compliant wheelchairs be dynamically sled impact tested. However, testing to evaluate the crashworthiness of wheelchair seating systems (WCSS) independent of their wheelchair wheel is not addressed by this standard, To address this need, this study developed a method to evaluate the crashworthiness of WCSS with independent wheels using computer simulation. To secure the safety, minimum strength requirements for the wheelchair are proposed based on the Federal Motor Vehicle Safety Standard (FMVSS) 207 regulation for the normal seats used in the vehicle. This test protocols, used to test the strength of motor vehicle seats, were modified and used to test the strength of wheelchair frame. Forward and rearward loads were applied at the WCSS center of gravity (CGSS), and a moment was applied at the uppermost point of the seat back. From the simulation, we could know a stress distribution by the applied load. As the result of this study, presents the criteria to minimize the injury of the wheelchair passenger and provides design guidelines to the manufacturers of wheelchair.
