On the basis of the research on the frame structure of the multi-point Forming machine, its finite element model and mathematical model have been set up. 摘要本文在对三梁四柱式多点成形压力机机架结构研究的基础上，建立了压力机机架有限元模型和机架结构优化的数学模型。
The hydroforming of Abnormity Tube can carry through in common hydraulic press or special hydroforming press. 异形管件液压胀形可以在普通液压机或专用液压胀形压力机上配以专用模具装置完成。
