상용차 운전석의 수동식 가변댐퍼에 대한 동적특성 해석

Dynamic Characteristics Analysis of A Manually-Controlled Damper for Driver's Seat of Commercial Vehicles

To improve the set comfort of commercial vehicles in various road conditions, it is necessary to design a seat shock absorber which can avoid the vibration zone imposing the discomfort feeling and fatigue on drivers. Through the vibration and dynamic analysis, a shock absorber that has 4 steps of damping ability is developed. Dynamic characteristics analysis of the seat damper is performed considering each valve and oil path for the design purpose.
