Abstract: The characteristics of on-off control based on
velocity-feedback for semi-active suspentions of vehicle are researched.
During the simulation, the characteristics of amplitude-frequncy for
different damping control rules are compared, the tremble phenomenon due
to the on-off control effect are analyzed. As conculusion, the new
damping control rule is presented, which takes the relative velocity of
damper as feedback signals of the on-off control, it able to prevent the
system from the on-off tremble ,and simple to be relized.
Key words: Semi-active suspention On-off control On-off tremble
