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.

Description

technical field [0001] The invention relates to the field of engine assembly, in particular to a single-objective optimization sorting method for fan blades based on triaxial moments. Background technique [0002] In a turbofan engine with a high bypass ratio, the fan rotor blades are the main components that generate thrust. They are often large in size, weight, and complex in shape, resulting in large differences in static moment. Due to the limitations of equipment capacity and cost, generally speaking, the fan blades do not participate in the balance with the fan rotor, and can only be installed after sorting according to the static torque during the final assembly process. This makes the measurement and sorting method of the blade moment have a direct impact on the final equilibrium state, and then have a key impact on the vibration of the whole machine when the engine is working. [0003] Sorting accuracy and efficiency are important indicators for evaluating the tech...
