Abstract

Patente de Invenção:<B>"AMORTECEDOR DE VIBRAçãO ADAPTAVELMENTE SINTONIZADO COM DUPLA FELXãO"<D>. Aparelho para neutralizar vibrações que inclui um alojamento para a conexão a um membro de vibração. Os primeiro e segundo corpos são conectados ao alojamento através das primeira e segunda molas, respectivamente, com uma rigidez combinada que define uma freq³ência ressonante na qual os primeiro e segundo corpos oscilam com relação ao alojamento. Cada uma das primeira e segunda molas incluem uma pluralidade de hastes fixamente conectada entre um par de anéis. Uma alavanca engata os primeiro e segundo corpos para variar um espaçamento entre esses corpos, quando a força originária de um atuador for aplicada à alavanca. A ação da alavanca altera a rigidez das primeira e segunda molas que varia a freq³ência ressonante do amortecedor de vibração.
