반능동 진동 흡수기의 자동차 시트 서스펜션에 대한 응용

The paper examines the ride performance enhancement that can be obtained by applying hydraulic semiactive vibration absorbers (SAV A) to alter the compliance characteristics of the seat/wheel suspension system. The work relies on a consistent model of the (nonlinear) hydrodynamics of the SAVA. A recently developed Lyapunov control scheme is used to provide regulation. The peIformance is first examined assuming a quarter car with a seat/seat mounted mass. The paper then employs a quarter car/seat with a two mass ISO model of the seated human. The simulated results indicated that a reduction of 45% of the peak vertical acceleration is achievable with the new system.
