STUDIO DI UN AMMORTIZZATORE ELETTROMAGNETICO A RECUPERO DI ENERGIA

2013

Questo lavoro ha come obiettivo principale lo studio teorico e con supporto di software F.E.M. di un dispositivo che consenta recupero energetico da una sospensione automobilistica. In sostituzione allo smorzatore viscoso, che dissipa l’energia cinetica del veicolo a seguito dell’attraversamento di strade sconnesse o ostacoli più marcati, si è usato uno smorzatore elettromagnetico che svolga le funzioni dello smorzatore viscoso consentendo un recupero di energia elettrica. Lo smorzatore elettromagnetico è di tipo a magneti permanenti e il suo funzionamento si basa sul fenomeno dell’induzione elettromagnetica. Il modello matematico descrive il funzionamento dello smorzatore, restituendo i va…

Settore ING-IND/14 - Progettazione Meccanica E Costruzione Di MacchineMain objective of this work is the theoretical study and support of FEM software of a device that allows for energy recovery from an automotive suspension. In replacing the viscous damper which dissipates the kinetic energy of the vehicle due to rough roads or obstacles more marked an electromagnetic damper is used that performs the functions of the viscous damper allowing a recovery of electricity. The damper is of the electromagnetic type with permanent magnets and its operation is based on the phenomenon of electromagnetic induction. The mathematical model describes the operation of the damper restoring the values of the electrical and mechanical magnitudes as a function of the relative speed between the rod and the stator. Energy recovery has been estimated considering an electric minicar that transits on a bumpy road. The recovered power has a total value of about 250W.

Structuration du territoire bourguignon : de l'île à l'isthme

2006

Three principles govern the structuration of the burgundian territory. Its internal organization, with the peripheral location of its most active areas, is similar to the organization of an island. Its situation within national and European space makes it an area of multiple transitions, an unsettled organization, submissive to strong centrifugal forces which can threaten its unity. Lastly, it has always been crossed by numerous links, it is an intermediate space between nodes, strongly marked with networks and exogenous traffic which criss-cross its territory.
