Prediction on milling distortion for aero-multi-frame parts
چکیده انگلیسی

Because the multi-frame component of an airplane has thin walls of variable wall thickness, and a high fitting accuracy is required, the prediction of its milling distortion is extremely important. In this study, the finite element model of the milling distortion analysis is established firstly for the multi-frame components, and the prediction analysis of the milling distortion under different milling conditions is carried out, by means of three-dimensional finite element simulation technology. Comparing the simulation results and the measurement ones of the milling distortion, the proposed model is modified and prediction method is proved to be effective. Software system is developed specially for the prediction of the milling distortion for aero-monolithic multi-frame components. By using of the software, a platform structure with 192 frames is analyzed and its milling distortion is predicted successfully.
