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

상용차 운전석의 수동식 가변댐퍼에 대한 동적특성 해석

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.
