An active suspension system optimizes the vehicle attitude and the tires' contact with road surfaces under any dynamic and static load and surface conditions.
This project deals with the design and construction of a prototype quarter-car
model of an active suspension system. The system consists of a sprung mass,
two linear springs, pneumatic cylinder and valving, along with position,
velocity, and acceleration sensors. An a.c. gearmotor driving a cam is
used to simulate a sinusoidal road surface condition. The signals from
the sensors are processed by a microcomputer which controls the pneumatic
valve via a solid state relay. The double port cylinder positions the sprung
mass in accordance with the correction signal.
