| To satisfy the urgent requirements of deep cavity components with complex surface in spaceflight, aviation and automobile fields, the multi-directional sheet hydroforming technology was proposed. The technical principle, deformation regulations and typical applications were discussed. The influence of multi-directional sheet hydroforming on the strain distribution, wrinkling behavior, forming limit and stress state of formed shells were investigated. The studies showed that this forming technology had a very broad application potential on the fields of forming limit and precision improvement, uniform thickness and deformation distribution, forming steps reduction, etc. |
