Abstract
UN ACTUADOR QUE INCLUYE UN ELEMENTO METALICO DE MEMORIA, UN MUELLE DE CONTRAACTUACION DE FUERZA SUSTANCIALMENTE CONSTANTE Y DE UN ELEMENTO ACTIVADO. EL ELEMENTO METALICO DE LA MEMORIA SE TRANSFORMA DESDE UNA ESTRUCTURA DE MARTENSITA HASTA OTRA DE AUSTENITA A UNA TEMPERATURA CONOCIDA. LA ESTRUCTURA DE MARTENSITA SE DEFORMA MAS FACILMENTE QUE LA DE AUSTENSITA. LA FUERZA APLICADA POR EL MUELLE DE CONTRAACTUACION ES SUFICIENTE PARA DEFORMAR LA ESTRUCTURA DE MARTENSITA A TRAVES DE LA GAMA DE TEMPERATURA DE TRANSFORMACION PERO INSUFICIENTE PARA DEFORMAR LA DE AUSTENSITA DE FORMA QUE AL MENOS UNA PARTE DE LA BANDA METALICA DE MEMORIA EXPERIMENTA UN GOLPE PREDETERMINADO EN RESPUESTA A LA TRANSFORMACION DE LA BANDA METALICA DE MEMORIA ENTRE LOS ESTADOS DE MARTENSITA Y DE AUSTENSITA. EL ELEMENTO ACTIVADO ESTA CONECTADO AL ELEMENTO METALICO DE MEMORIA PARA MOVERSE CON ELLA.
