The Ideal

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.

Ring Net

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.

Abstract The automotive industry is facing new environmental requirements that call for more stringent rules to protect the environment and reduce material and resources usage. As such, the automotive industry is in more need to reduce fuel consumption and control emissions in order to meet the new environmental requirements. One of the methods that helps in acheiving lower fuel consumption targets is weight reduction. Making cars lighter sounds plausable, but is it acheivable without affecting vehicle Safety as well as other customer demands for more comfort and better vehicle performance (Criteria that are a must in today’s stringent safety requirements and competitive environment.). The body-in-white (BIW) accounts for about 25% of the total vehicle weight, and thus it provides a great opportunity for weight reduction. However, the challenge is not only to reduce the vehicle’s BIW weight, but also to maintain competitive vehicle functionality in Safety, NVH and Durability. The studied technologies include: Generic Body Architecture, Tailor Welded Blanks, Ultra High Strength Steel, Structural Foams, and Structural Adhesives. Each of these technologies was benchmarked in terms of weight savings, vs Safety, NVH, and Durability functionalities. The models that were used for the technology prove outs are based on generic modified Body Architecture CAE models. It was shown that the total weight savings acheived from architecture alone was 24 lb (out of 707 lb initial BIW weight, thus making the weight savings close to 3.4%). In addition, the combination of Tailor welded blanks and Ultra high strength steel has resulted in an 80 lb reduction in the BIW weight, which is close to 11.3%. Structural foams showed an effective increase in roof crush strength, and showed potential enhancement for frontal crash pulses as well as potential shortening of front ends. On the other hand, structural adhesives showed enormous NVH benefits in stiffness with as little as 1% energy absorption enhancement for crash. Thus producing the perfect method to compensate the reduced body stiffness due to sheet metal gage reduction and replacement with Ultra High strength steel. By such both safety and NVH functionalities are complemented without weight increase.
