This paper addresses the vibration reduction of a simple structure, simulating a workpiece carrier plate, through a cancellation technique based on the use of smart compensation actuators. The proposed compensation strategy is implemented resorting to magnetostrictive actuators acting far from their resonant frequencies. Specifically, the procedure has been tested on two test rigs designed with particular reference to machine tools applications: they require the use of one and three magnetostrictive actuators for 1D and 3D vibrations compensation. The parameters of the compensation strategy are identified from the direct characterization of the actuators embedded in the structure. The resulting reduction of the lateral vibrations of 1D and 3D plates in the frequency range up to 400 Hz proves to be very satisfactory

Abstract
This paper addresses the vibration reduction of a simple structure, simulating a workpiece carrier plate, through a cancellation technique based on the use of smart compensation actuators. The proposed compensation strategy is implemented resorting to magnetostrictive actuators acting far from their resonant frequencies. Specifically, the procedure has been tested on two test rigs designed with particular reference to machine tools applications: they require the use of one and three magnetostrictive actuators for one-dimensional (1D) and three-dimensional (3D) vibrations compensation. The parameters of the compensation strategy are identified from the direct characterization of the actuators embedded in the structure. The resulting reduction of the lateral vibrations of 1D and 3D plates in the frequency range up to 400Hz proves to be very satisfactory.File | Dimensione | Formato | |
