Abstract

"RESTRIçãO CONTROLáVEL E ABSORVEDOR DE CHOQUE". Uma passagem de fluxo de fluido hidráulico tem uma restrição controlada disposta na passagem. A restrição inclui um primeiro filtro, um segundo filtro e uma pluralidade de partículas dispostas entre os dois filtros. As partículas são partículas dielétricas ou elas são partículas magnetizáveis. As partículas dielétricas criam um fluido eletro-reológico entre os filtros e as partículas magnetizáveis criam um fluido magneto-reológico entre os filtros. O arranjo para as partículas dielétricas é controlado por um campo elétrico e o arranjo para as partículas magnetizáveis é controlado por um campo magnético.
