Tuning passive, semi-active, and fully active suspension systems

Abstract

A quarter car model is used to investigate the tuning of the damping for passive, on/off semiactive, continuously variable semiactive, and fully active suspensions. For the semiactive and fully active suspensions, the control algorithms are limited to feedback schemes based on absolute and relative velocity measurements. Ride comfort, road holding, and suspension travel are investigated with random input velocity to simulate road roughness. The application of a disturbance force to the sprung mass is used to investigate body control.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
