Reducing automobile weight has been necessarily accelerated to save energy and improve drivability. Accordingly, use of high strength steel and hollow sections help in weight reduction. In this study, the effect of trapped oil has been investigated to improve the metal flow in upsetting of a hollow workpiece using no mandrel. It was found that the ideal deformation without friction between the dies and the workpiece was nearly achieved when a low and thick ring with trapped oil was upset. The inner diameter of the oil-filled ring was expanded more than that of the benchmark ring. The effect of the expansion of the ring and the reduction of the friction proved helpful in trial forming of a gear preform.

In this study, research was conducted on the development of Ring-Net, a major component of the Ring-Net System for the localization of a high-level debris-flow barrier, which is fully applied with foreign technology. Ring-Net was constructed using the 2,040 MPa class high-strength steel wire with a 2.8 mm diameter,. Its performance was verified through simulation and a 3-Ring Test (ETAG 027). As a result, the 3-Ring breaking load of 7-19/2.8/300 Ring-Net was analyzed to be 79.8-329.0 kN. The 3-Ring energy dissipating capacity was 2.9-8.7 kJ, which is equivalent to the performance of the Ring-Net made of 1,770 MPa class wires with a 3.0 mm diameter. However, since it can be manufactured with a 13% weight reduction compared to the existing technology, it is believed to be advantageous for lightening the high-level Rockfall & Debris Barrier and improving its construction capability.
