摘要
Abstract
The method how to determine the dimensions of fuselage panel under bending moment was introduced. The formula for calculating stress and dimensions was deduced based on the simplified model of typical fuselage structure. After the opitmization analysis using formulae,the panel parameters which satisfied the strength requirements were obtained. It was found that the formula results greatly fit the the FEM results from Msc.Nastran software. This method can achieve the rapid optimization on fuselage panel under bending moment and guide the preliminary structure design.关键词
