摘　　要：通过计算机模拟技术和借鉴钢材半球壳成形工艺设计了深潜器载人舱用钛合金半球壳的整体冲压成形模具及成形工艺,并以钢材、纯钛的半球壳整体冲压预成形试验来优化工艺参数,最终成功冲压出深潜器载人舱用TC4ELI钛合金半球壳。经检测,整体冲压成形的TC4 ELI钛合金半球壳尺寸和力学性能均满足深潜器载人舱用钛合金球壳设计指标,可用于制造4 500 m深潜器载人舱。The titanium alloy hemisphere shell stamping forming mould and forming process of manned submersible were designed by computer simulation techniques based on forming process of steel hemisphere shell, then the mould and forming process parameters were verified and optimization through the tests by steel and pure titanium slabs, TC4 ELI titanium alloy hemisphere shell of bathyscaph was successfully produced by stamping forming process. The tested results indicate that the dimension and mechanical properties of hemisphere shell produced by overall stamping forming can meet the design indicators of the 4 500 m manned bathyscaph and can be used for manufacturing the hemisphere shell of manned bathyscaph
