A modular active bearing for noise reduction of rotating machinery
نویسندگان
چکیده
Traditionally, active control of structural radiators has approached the problem through integrating sensors and actuators on or into the structure. In such an approach, the goal is to modify the systems response to disturbance, rather than influence the disturbance path to the radiating structure. Many practical issues exist, which ultimately limit the effectiveness of such an approach. A general problem in industry is noise radiation from a structure housing a rotating device, where the rotating device creates the disturbance. We have attacked the problem by seeking to reduce the force transmission in the path rather than the vibration on the radiating surface itself.

Active structural acoustic control of rotating machinery using an active bearing
This paper presents an active bearing for reducing the radiated noise of rotating machinery. This modular bearing uses piezo stacks for actuation and both force and acceleration measurements as sensing signals. The bearing is tested on an experimental test bed comprising a rotating shaft, which is mounted in a frame. Noise is radiated by a plate that is attached to the frame. The set-up is desi...
متن کاملA modular bearing with internal piezoshunt damping
When a piezoelectric transducer is incorporated in a mechanical structure, it is possible to damp the structural vibrations of the base structure by passive energy dissipation in the electrical domain [1]. Due to the strong electromechanical coupling in piezoelectric elements, the mechanical energy can be efficiently converted to electrical energy. By shunting the piezoelectric element to a pas...

This paper presents an axisymmetric rotational inertia shaker for reducing the structure borne noise radiated by rotating machinery. This modular inertia shaker uses a piezostack to generate a compensating force on a rotating element by accelerating a ring shaped mass. The piezostack is controlled using an adaptive shunt circuit, which emulates the impedance of a variable inductance. The inerti...
