某车型扭力梁零件的充液成形工艺研究

摘要

Torsion beam is a common part of vehicle rear suspension system. Its cross section is complex, so it is suitable for tube hydroforming. This paper analyzes the tube hydroforming process. And the effect of pre-forming and internal pressure on the forming effect of the parts is mainly studied. Finally, the trial production of the sample is completed.%扭力梁是汽车后悬挂系统中一种常见的零件,其截面变化复杂,因而适用于管材充液成形.文中分析了其充液成形工艺,并重点研究了预成形和内压力对零件成形效果的影响,最终完成样件的试制.
