Abstract
LA INTEGRIDAD DE FATIGA DE MATERIALES METALICOS PUEDE SER DETERMINADA POR UNO DE DOS METODOS. EN UN PRIMER METODO, SE INTRODUCE UN IMPULSO ENERGETICO EN EL MATERIAL METALICO, MEDIANTE POR EJEMPLO IMPACTANDO EL MATERIAL METALICO (20), Y SE DETECTA LA VIBRACION INDUCIDA Y SE ANALIZA PARA COMPUTAR EL FACTOR DE AMORTIGUACION DEL MISMO, ESTANDO ESTE DIRECTAMENTE RELACIONADO CON SU FATIGA. CON ESTE METODO, UN TRANSDUCTOR (28) VA UNIDO AL MATERIAL METALICO Y SU SALIDA ES AMPLIFICADA MEDIANTE UN AMPLIFICADOR (30) ANTES DE SER INTRODUCIDO EN UN ORDENADOR (22) QUE DETERMINA EL FACTOR AMORTIGUANTE. EN UN SEGUNDO METODO, UNA ENTRADA DE ENERGIA CONTINUA ES PROPORCIONADA AL MATERIAL METALICO, MEDIANTE POR EJEMPLO LA UTILIZACION DE UN GENERADOR DE FRECUENCIA UNIDO AL AMPLIFICADOR DE ENERGIA CUYA POTENCIA DIRIGE UN TRANSDUCTOR TAL COMO UN ALTAVOZ O SIMILAR PARA INDUCIR UNA VIBRACION CONTINUA EN EL MATERIAL METALICO. ESTA VIBRACION CONTINUA SE MIDE CON UN TRANSDUCTOR, UN AMPLIFICADOR, Y UN FACTOR AMORTIGUANTE CALCULADO CON UN ORDENADOR COMO EN EL METODO ANTERIOR.
