description | The traditional flight load modeling method of complex structure aircraft has the problems of large error and low efficiency. A flight load improved modeling method is proposed,which is comprehensively considering the influence of the bridge index and load equation index on the load model. Taking the multi-beam and multi-wall structure as an example,the load model based on the wing ground load calibration test data of a certain type of aircraft is built. The bending moment and shearing force of improved method and traditional method are compared.The model obtained by the improved method is verified with flight test data. The results show that the flight load improved modeling method is suitable for the load modeling of complex structure aircraft. The improved method can improve the accuracy and iterative stability of the load model while processing ground test data and the load model obtained by the improved method can be used for flight load measurement and safety monitoring. |
