Exploration of the material transfer effect in local loading forming of ultra-large-size integrated component with multi-rib

摘要: Isothermal local loading forming is a less-loading and flexible forging technology, which promising to form the ultra-large-size integrated component with multi-rib by adopting small tonnage equipment. Due characteristic, material in region can transfer into unloading transitional region. Identifying affect of important control flow obtain high-quality components under way. In this work, phenomena are explored boundaries clarified. Firstly, after each step analyzed displacement field strain based on finite element simulation ultra-large component. Meanwhile, velocity vectors during observed. Secondly, variations volume different zones revealed. Subsequently, change located far from die partition line analyzed. Furthermore, induced problems effect, i.e., folding additional strain, elaborated. Finally, between first/second zone determined. The verified using an eigenstructure FE physical experiment.
