Abstract

This paper describes an active control system intended to minimize the vertical vibrations transferred from the vehicle seat to the head. This system controls mechanical properties effectively such as the spring constants and damping coefficients of the seat cushion by using an optimized algorithm that comprises vibration analysis and an optimization method. To estimate an efficient optimized algorithm, we investigate reduction rates of the vertical vibrations on the head using a vibration analysis based on a model for the seat-occupant system when the mechanical properties are controlled in a part of seat cushion. These results showed relationships between the reduction rates and the mechanical properties of the each seat cushion optimized at frequency band. In conclusion, the effective optimized algorithm using these relationships enable to reduce the vertical vibrations on the head while reducing the number of seat cushion control.
