In order to reduce the deviation between the modal response results of the finite element model and the actual model of the helicopter rotor blade structure, a model updating method based on sensitivity analysis was used. In view of traditional sensitivity method without consideration of the influence of the change of design parameters on the sensitivity calculation results, as well as the problem of non-uniform quantification, the method was appropriately improved for the helicopter rotor blade model. Taking the carbon fiber composite helicopter rotor blade model as an example, the natural frequencies of the first six modes of the actual model and the finite element analysis model were obtained through experiments and finite element analysis, respectively, and the main design parameters of the finite element model of the rotor blade were optimized by using the sensitivity method. The average error between the rotor blade finite element model and the actual model was reduced from 8.15% to less than 1%. The error was significantly reduced and the accuracy was significantly improved. The updating results showed that the model updating method based on sensitivity analysis can effectively improve the accuracy of the helicopter propeller structure model.
