| 英文摘要: |
| Hydroforming processes have become popular in recent years, due to the increasing demands for forming lightweight or complicated components in the nuclear power, aerospace and automotive industries. This technology is almost new as compared with rolling, forging or stamping, therefore there is a lack of knowledge available for the product or process designers. Comparing to traditional manufacturing via stamping and welding, sheet and tube hydroforming tenders various advantages, such as reducing the cost of workpiece, tools and product weight, improving product’s stability and increase of the stiffness and strength of the formed parts, more uniform thickness distribution, fewer secondary operations, etc. State-of-the-art and recent developments of sheet hydroforming and tube hydroforming are discussed in details especially tube pulsating hydroforming and high-energy-rate impact hydroforming which are considered as novel processes in hydroforming technology. In addition, applications, technical issues, deformation mechanisms, process parameters are explored in details. The research results indicated that the novel hydroforming processes can make full advantage of the idea of “simultaneously controlling the shape and performance”, avoid the material instability and defects during the hydroforming process and improve the formability on tube and sheet specimens. Therefore, pulsating hydroforming and high-energy-rate impact hydroforming will be expected to be widely used in the field of automobile and aerospace in the future. The research results showed that, pulsating hydroforming and high-energy-rate impact hydroforming is expected to be used widely in different industrial sectors in near future. |
