| Abstract: | Tube hydroforming is a process to manufacture lightweight components, especially automotive parts, with advantages of cost and weight reduction, better structural integrity and increased strength and stiffness over the conventional process. In this paper, an investigation is conducted to the effect of the feeding pressure on experiment of hollow crankshaft hydroforming. One of typical failure modes such as wrinkling and splitting occurred due to unreasonable pressure is analyzed. The zone of hydroforming process window is confirmed. The important of friction lubrication in tube hydromorming is pointed out. |
