| 英文摘要: |
| Electrohydraulic forming (EHF) is a typical high speed forming technology that can be used to significantly improve the formability. It has the advantages of single die, high flexibility and high surface quality of parts, etc. Therefore, EHF technology is playing an important role in the field of precision forming of thin wall parts made of high strength sheet metal. In this work, we introduced the principle and main characteristics of EHF technology, summarized the research status of EHF technology and the two-step EHF method, and analyzed the formability sheet metal by EHF process and its influence factors. Finally, the main points in the theory and application research of EHF technology were presented and the development trend was forecast. |
