  2. 11. Active suppression of vibration and noise in industrial applications

    Author : Linus Andrén; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active control technology; Active vibration control; Noise suppression;

    Abstract : Today, active control technology is about to emerge from the research labs into products in various areas. It has become an attractive method where passive techniques have low impact at low frequencies and adding active control to that part is often an attractive solution. READ MORE

  4. 12. Analysis of Structural Dynamic Properties and Active Vibration Control Concerning Machine Tools and a Turbine Application

    Author : Henrik Åkesson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Vibration Control; Structural dynamics; Nonlinearities; Turning; Milling;

    Abstract : Vibration in metal cutting is a common problem in the manufacturing industry, especially when long and slender tool holders or boring bars are involved in the manufacturing process. Vibration has a detrimental effect on machining. In particular the surface finish is likely to suffer, but tool life is also most likely to be reduced. READ MORE
