Abstract

Amortiguador de fricción basado en elastómeros magnético.#La presente invención hace referencia a un amortiguador que emplea un elastómero magnético como elemento que ejerce una fuerza de fricción en el dispositivo. El elastómero magnético puede estar compuesto por organosiloxanos, poliuretanos, aceite de silicona, aditivos o una mezcla de estos componentes y partículas magnéticas de hierro, de temario tanto manométrico como micrométrico. El amortiguador posee en su interior una o varias bobinas, que son capaces de generar un campo magnético que modifica las propiedades reológicas del elastómero magnético, así como en su magnetostricción.Friction damper based on magnetic elastomers. # The present invention refers to a shock absorber that employs a magnetic elastomer as an element that exerts a frictional force on the device. The magnetic elastomer can be composed of organosiloxanes, polyurethanes, silicone oil, additives or a mixture of these components and magnetic particles of iron, both symmetrical and micrometric. The damper has one or more coils inside, which are capable of generating a magnetic field that modifies the rheological properties of the magnetic elastomer, as well as its magnetostriction.
