Optimization method for electromagnetic compatibility fault repair by adopting electromagnetic compatibility test over-standard strategy

Abstract

The invention discloses an optimization method for electromagnetic compatibility fault repair by adopting electromagnetic compatibility test over-standard strategies. In the method, a conducted emission curve, a conducted susceptibility curve, a radiated emission curve and a radiated susceptibility curve are used and are respectively compared with requirements of national military standards to obtain over-standard areas; according to electromagnetic vulnerability weights of different frequency ranges, an area weighted integration method is adopted to quantify the over-standard areas to obtain respective weights; and finally the respective weights are introduced to obtain electromagnetic compatibility weight expected values of helicopter-borne equipment. By virtue of index quantification and weight allocation, the electromagnetic compatibility interference faults of the helicopter-borne equipment are associated with the electromagnetic compatibility of the entire helicopter, factors such as electromagnetic compatibility conducted emission, conducted susceptibility, radiated emission, radiated susceptibility and electromagnetic compatibility classification of all helicopter-borne equipment are comprehensively considered, the index quantification and the corresponding weight allocation are conducted to obtain degrees of influence of the electromagnetic compatibility interference faults of the helicopter-borne equipment on the electromagnetic compatibility of the entire helicopter are obtained, the priorities of the repair sequences of the electromagnetic compatibility interference faults of the helicopter-borne equipment are determined and a basis is provided for determining sequences for electromagnetic compatibility rectification.
