MR 댐퍼를 갖는 세미-액티브 시트 서스팬션 시스템의 수학적 모델링 및 특성해석에 관한 연구

The suspension system is to be classified into two types. One is the suspension installed between a car-body and a wheel. It is used for coupling a car-body and a wheel and decrease shock from the road surface. The other type called the seat-suspension is installed under the seat. The seat Suspension systems are widely used in off-road machinery to reduce the vibration transmitted from the vehicle floor to the vehicle operator. The drivers are often exposed to high level of low-frequency vibrations due to the unevenness of the ground. These harmful vibrations, aggravated by dicult working conditions (uncomfortable postures, inappropriate seats, frequent handling operations, etc...) lead frequently to spinal disorders. This paper, which is the fundamental study, will conclude with a discussion of the mathematical modeling and characteristic analysis of seat Suspension system with and without MR damper.
