摘      要：Combining the design of experiments(DOE)and three-dimensional finite element(3D-FE)method,a sequential multiobjectiveoptimization of larger diameter thin-walled(LDTW)Al-alloy tube bending under uncertainties was proposed andimplemented based on the deterministic design *** the fractional factorial design,the significant noise factors are obtained,viz,variations of tube properties,fluctuations of tube geometries and *** the virtual Taguchi’s DOE of inner and outerarrays,considering three major defects,the robust optimization of LDTW Al-alloy tube bending is achieved and *** thebending tools,the robust design of mandrel diameter was conducted under the fluctuations of tube properties,friction and *** the processing parameters,considering the variations of friction,material properties and manufacture deviation ofmandrel,the robust design of mandrel extension length and boosting ratio is realized.

主 题 词：robust optimization tube bending uncertainty aluminum alloy multi-objective optimization
