시트의 동특성을 이용한 동적 안락감 평가

초록

The seats is one of the important components affecting dynamic comfort cognized by a passenger. To analyze dynamic characteristic of a seat for vehicles operating on various road conditions, the seat vibration from road irregularity should be unders tood and compared. It is necessary to study the relationship between evaluation of dynamic comfort and dynamic properties of the seat for design of seat comfort. In this study, an experimental method to determine the dynamic properties of polyurethane foam is proposed to analyze the seat characteristics. The beam transfer function method is used to obtain the dynamic properties of the foam. The measured transfer function is compared with the predicted and simulated one.
