摘要
Abstract
The nonlinear vibration response prediction of aircraft structure using computer technology is of great significance to the vibration flight test digital development.Based on the helicopter vibration response in a flight test,from the perspective of time series,Back-Propagation neural network is used to establish a nonlinear vibration response prediction model.After verifying the effectiveness of the model in stable and maneuvering flight movement,the heading,lateral and vertical vibration values of the helicopter structure in different flight movements were predicted,and the influence of the prediction step size on the prediction accuracy of the model was analyzed.The research results provide reference for the application of structural nonlinear vibration response prediction models in flight tests.关键词
