Conception d'un amortisseur de vibrations magnétique à raideurs ajustables

Abstract : This study deals with the design of a magnetic vibration absorber. The vibrating magnetic mass is placed in a magnetic field created by fixed permanent magnets. The resulting linear and nonlinear stiffnesses can be controlled by adjusting the relative positions of the static magnets. The equations of the model of the damper are obtained using a multipole expansion. The proposed magnetic absorber can be used as a tuned mass damper, a nonlinear energy sink or a bi-stable vibration absorber. These 3 cases are experimentally observed using static force measurements.
