| 摘 要： | 利用数值模拟对Y型三通管内高压成形过程进行了研究,研究了87MPa～145MPa范围内5条不同内压的加载路径的成形过程,分析了过渡区内凹、支管高度不足等缺陷产生的原因和内压为116MPa时零件成形过程中典型位置的壁厚变化,以及内压对零件壁厚分布的影响。数值模拟结果表明,106MPa～126MPa为成形Y型三通管合适的压力区间,但不同内压成形的零件最小壁厚不同。

| Abstract: | A numerical simulation analysis has been conducted for hydroforming of Y-shaped tubes. Five loading paths with different internal pressure from 87MPa to 145MPa have been used. Failure modes are analyzed such as the transition zone is depressed and the height of branch-tube is not enough. The thickness of specific spots is analyzed for different stage of hydroforming when internal pressure is 116MPa, The influence of internal pressure on thickness distribution of parts is discussed. Through numerical simulation it is indicated that 106MPa-126MPa is a reasonable range for hydroforming of Y-shaped tubes, but for different internal pressure the min thickness of parts is different. |
