Designed one kind of active vibration absorber used for pipe using on ships. This paper first introduced the characteristics and classification of inertial actuators, then give the mathematics model and transfer function of active vibration absorber, the control system and control algorithm is presented thoroughly as well, finally give the simulation results. The simulate results shows that this system can decrease the vibration of pipe system effectively;the decrease of harmonic frequency is in the range between 10 dB and 25 dB.
