Abstract

METODO DE ACUMULACION DE DAÑOS POR ESFUERZOS MECANICOS EN UN ROTOR DE ALTA PRESION, DEBIDOS A DIFERENCIAS DE TEMPERATURA. CONSISTE EN UTILIZAR UNA REPRESENTACION DEL DAÑO POR ESFUERZOS CORRESPONDIENTE A UN PERIODO DE CAMBIO DE TEMPERATURA CONTINUO, EN EL QUE SE INCREMENTA UNA VARIABLE DE CONTADOR ASOCIADA CON LA REPRESENTACION DEL DAÑO POR ESFUERZOS CADA VEZ QUE HAY UN CAMBIO SIGNIFICATIVO EN UNA CIERTA DIRECCION DE CAMBIOS DE ESFUERZOS INDUCIDOS EN EL ROTOR. EL DAÑO ACUMULADO POR TALES ESFUERZOS SE CALCULA SUMANDO LOS PRODUCTOS DE CADA VARIABLE DE CONTADOR MULTIPLICADA POR UN COEFICIENTE DE DAÑOS POR ESFUERZO MECANICO CORRESPONDIENTE A ESA VARIABLE DE CONTADOR Y DE SUMA AL DAÑO POR ESFUERZOS ACUMULADO PREVIAMENTE, CALCULADO ANTES DE LA REPOSICION DE LAS VARIABLES DE CONTADOR, A FIN DE PROPORCIONAR EL DAÑO POR ESFUERZOS ACUMULADO TOTAL.
