자동차 시트벨트의 과도응답 특성에 관한 연구

Abstract

In recent years, as a consequence of the technological advancements in the automobile industry andchanges in consumer demands, the reduction of noise inside vehicles rather than vehicle performance hasincreasingly become an important factor of interest. To date, most studies have focused on noise andvibration reduction techniques for the engine and drive system of vehicles. In this research, a comparativeanalysis for reducing the effect of vehicle seatbelts on the transient response is performed using the test ofvehicle conditions and transient response analysis in accordance with seatbelt conditions. After the sensitivityanalysis, the specifications for improvement were designed based on the transient response analysis. It wasconfirmed that the transient response characteristics were improved by the transient response analysis andvehicle conditions test. Through computer-aided engineering, the transient response characteristics of seatbeltswere checked with less cost and time.
