Development of the Stretcher with the Vibration Isolator Using Nonlinear-Structure

Abstract

During ambulance or stretcher transport, subjects experience vibration causing discomfort or pain. Measures must thus be taken against such vibration. The purpose of this study was to develop stretchers that minimize vibration during transport. This study first details vibration size, direction, and frequency through vibration measurement experiment, resulting in a nonlinear stretcher using a vibration isolator. Stretcher performance was then evaluated and confirmed RMS and acceleration PSD.
