Abstract

DISPOSITIVO PARA ENSAYO DE FATIGA DE UN ORGANO MECANICO.CONSISTE EN: A) UTILIZAR UN CAPTADOR O SENSOR (4) DE DESPLAZAMIENTO QUE MIDE LAS DEFORMACIONES DEL ELEMENTO SOMETIDO A LOS ENSAYOS (1) Y PROPORCIONA UNA SEÑAL ELECTRICA SINUSOIDAL; B) UTILIZAR UN CIRCUITO DIVISOR ANALOGICO (7) QUE RECIBE EN SU ENTRADA DE NUMERADOR (8) ESTA SEÑAL ELECTRICA, Y EN SU ENTRADA DE DOMINADOR (6) UNA SEÑAL DE VALOR EFICAZ, PROPORCIONADA POR UN CONVERTIDOR DE UN VALOR EFICAZ (5) ALIMENTADO IGUALMENTE POR LA SEÑAL DEL CAPTADOR (4). LA SALIDA (9) DEL CIRCUITO DIVISOR, FILTRADA (10)Y AMPLIFICADA (12), ALIMENTA EL EXCITADOR ELECTROMAGNETICO (13) QUE ACTUA SOBRE EL ELEMENTO (1) SOMETIDO A ENSAYOS. LA SEÑAL DE VALOR EFICAZ PUEDE SER UTILIZADA PARA LA REGULACION DEL NIVEL DE LA SEÑAL QUE ALIMENTA EL EXCITADOR (13).
