Abstract: The
mathematic model of semi-active suspension with time-delay is built. The
theory analysis and the calculational methods of the critical time-delay
of the semi-active suspension with time-delay are discussed, and
according to those, the tunable damper and control system of semi-active
suspension are designed. Based on that, the bench test of 1/4 model of
semi-active suspension system is done. The effect of time delay in the
control path on dynamic performance of semi-active suspension equipped
with fuzzy control is studied. The calculation is the basal same as the
test. It is the foundation for the study of destabilizating mechanics
and stability control of semi-active suspension.
Key words: Time-delay
