ACTIVE VIBRATION ISOLATION FOR A DIESEL ENGINE GENERATOR IN MARINE APPLICATION

摘要：

　　An active vibration isolation system is developed for a diesel engine generator in a floating tug boat. This system consists of six inertial actuators and a DSP processor. A six-input and six-output adaptive control strategy is applied and the reference input signal comes from a laser tachometer on the shaft of the diesel. Six accelerometers are located on the top of isolators to act as error sensors. A hydrophone is dropped in the sea water to measure the underwater radiation from the diesel generator. The active vibration isolation experiment is conducted in the tug boat when only the diesel engine generator is working. The experimental results demonstrate that good reductions are obtained not only for vibrations of error sensor’s locations but also outputs of the hydrophone which is dropped in the water under the hull. Some discussion and conclusions are given at last.
