| description | Active suspension is a term where active components are incorporated in
a mechanical suspension system. Compared to passive suspension, the
active suspension provides improved feature of suspension in terms of ride
quality and vehicle handling. While the passive suspension consists of
spring and dampers, the active suspension comprises of sensors, actuators
and controller with passive system. The actuator in the active suspension
provides forces to the suspension which eventually improves ride performance
and comfort.This paper presents the early stage of modeling an
active suspension of a railway vehicle. The mathematical model of the
system is demonstrated and the early suspension control of the vehicle
is introduced. As a start only the quarter car vehicle is considered and
tested upon random or irregular track input at a speed of 31 m/s. The
skyhook control strategy is introduced to the suspension, making it an
active system. The performance is then compared to the passive. Preliminary
results have shown that the active suspension improves ride quality
by reducing the vehicle body accelerations and suspension deflections. |
