Abstract

The invention provides a fan blade single-target optimization sorting method based on three-axis torque, which comprises the following steps of: S1, adopting sorting software to carry out sorting preprocessing, construct equivalent resultant torque and establish an initial sequence; and S2, carrying out loop iterative operation by using a sensitive area search algorithm integrated in the sorting software to obtain an optimal sorting sequence of the equivalent unbalance. The concept and method of'equivalent resultant moment 'are constructed, three moment values are synthesized into a single moment, a multi-objective optimization problem is converted into single-objective optimization, optimization problem processing is simplified, and calculation is facilitated. Meanwhile, by analyzing the unbalance effect generated by the moments in different directions and combining conversion between a fan rotor supporting structure and static/even unbalance, the axial moments of the blades are subjected to weighting processing, and the problem of moment synthesis weight distribution is solved.
