Improvement of Seat Comfort by Reducing the Human Vibration
인체진동을 고려한 시트 안락성 향상
Abstract
The purpose of the work is to improve comfort of a car seat, especially dynamic comfort which affects driver's discomfort during the long time driving. Definition of dynamic comfort was made before the investigation of which parameter affects seat comfort. In order to optimize design parameters so as to maximize seat comfort as well as to know the cause of discomfort, benchmarking on a target vehicle and competitive vehicles was performed, which showed both the vibration transmission characteristics and the compression set due to dynamic loading should be reduced. As a solution ball rebounds was increased by about 10% of the original foam, which showed reduction of S.E.A.T. value by 10% and of compression set by 60%.
