Abstract: Air inlet structure design is essential for fighter to ensure the safety and usage cost control during the whole life. The air inlet structure strength simulation analysis technology based on geometrical nonlinearity and globle-local strategy of solution is emphasized. It is verified via an example that the method enables to improve the quality of air inlet structural strength and the success probability of first time with lower cost.
Keywords: the structural mechanics of flight vehicle, air inlet, strength design , geometry nonlinearity, simulation.
