    Abstract: Wind energy has become one of the most cost-effective and environmental friendly renewable energy resources among all exploited renewable energy. However, the failure of gearbox contributes most of the downtime for wind turbine system. Dynamic properties of drivetrain, including gearbox should be investigated in detail further. In present paper, a ... Show More

    Abstract: A control strategy is presented incorporating friction which can be adapted within a cycle of vibration. During base shock input, the friction is switched on and off based on specified response parameters. The predicted response of a semi active system is compared with that of a passive isolation system. The strategy is shown to produce an improved... Show More
