Abstract
In the design of advanced aircraft turbofan engine, applying the continuous fiber reinforced metal matrix composites(MMC), which have excellent properties of good mechanics, resistance to high temperatures and light mass, to manufacture some of the key components is the effective way to realize thrust increase and weight decrease. In order to realize the design and analysis to the structural integrity of this sort of composite components, with the continuous fiber reinforced metal matrix composites low pressure turbine(LPT) shaft structure as the object of study, mesoscopic mechanics method is applied to calculate mechanics properties of continuous fiber reinforced MMC; On this basis, applying composite mechanics parameters calculated by representative volume element (RVE) model as input value, meanwhile, from the point of mesoscopic mechanics method like the specific arrangement mode of fiber and matrix and the mechanics properties of MMC shaft to analyse response regularities of MMC shaft modal frequency that caused by variation of fiber volume content, layer angle, layer amount and boundary conditions of the shaft structure.
