Abstract
The paper examines the ride performance enhancement that can be obtained by applying hydraulic semiactive vibration absorbers (SAVA) to alter the compliance characteristics of the seat/wheel suspension system. The work relies on a consistent model of the (nonlinear) hydraulics of the SAVA. A recently developed Lyapunov control scheme is used for regulation. The performance is 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. Two road conditions are employed in the simulations; a ride swell and a road surface with a white noise velocity profile. The results show 45% reduction of of the vertical acceleration.
