Summary:The invention relates to a design method of a super-plastic forming hollow twisted blade. The design method comprises the steps that a multi-load multi-objective function is obtained through calculation on the basis of a three-dimensional finite element analysis model comprising the full technological process of twist forming, hot forming and super-plastic forming, optimal forming parameters including geometrical parameters and technological parameters are obtained, and finally the hollow twisted blade with the optimal structural state and internal rib geometrical parameters is obtained. According to the design method, the research period of new products is greatly shortened, the design and manufacture precision is improved, the efficiency and the product quality are improved, the design method not only can be used for manufacturing the hollow twisted blade, but also can be used for designing and manufacturing various titanium alloy, aluminum alloy and high-temperature alloy structuralparts with complex shape
