摘要
系统地介绍了管材液压胀形技术,包括工艺设备、应用情况、发展趋势等,重点指出了管材液压胀形的成形关键是解决加载路径问题,同时对成形失效形式进行了分析.
Tube hydro-forming is studied systemically, including technology and equipment, application states, development trends and so on. The key issue of tube hydro-forming is the resolving of loading path which is pointed out emphatically and the failure modes of forming are also studied.
