Advanced High Strength Steels (AHSS) are now commonly used in automotive body structural applications. The high strength of this grade classification is attractive to help reduce mass in the automotive body through reduction in thickness. Strength also supports improvements in safety requirements so that mass increases are minimized. In some specific grades of AHSS, energy absorption is possible in addition to the high strength. This course will review the definition and properties of AHSS and cover several common applications in automotive body structures.

The emission regulations for mobile on- and off-road applications are becoming stricter in Euro 6/Stage 5 and beyond levels and require the use of SCR for NOx and diesel particulate filter (DPF) for PM removal. The presence of wall-flow filter with active regeneration creates a risk of thermal deactivation of SCR catalyst in the aftertreatment system (ATS). The thermal and chemical durability of Cu- and Fe-SCR catalysts were screened and developed to stand these conditions. The performance of catalysts were investigated with laboratory simulations and engine-bench equipments. New Cu-SCR catalysts have a very high low-temperature SCR activity and a low dependency on NO2 promotion. Developed Fe-SCR catalysts showed also an improved low temperature activity and durability but were more dependant on NO2 concentration too. Low N2O formation with Cu-SCR catalyst is a key factor to minimize green house gas emissions.

This paper presents an approach to how existing production systems can benefit from Industry 4.0 driven concepts. This attempt is based on a communication gateway and a cloud-based system, that hosts all algorithms and models to calculate a prediction of the tool wear. Refill Friction Stir Spot Welding is a sub-section of friction welding, where a rotating tool that consists out of three parts is used to heat up material to a dough-like state. Since Refill Friction Stir Spot Welding produces a selective dot-shaped connection of overlapping materials, the production requirements are similar to riveting or resistance spot welding. In contrast to other bonding techniques, Refill Friction Stir Spot Welding can be integrated within the production process without major interferences or changes.

A trend in automotive parts development is the pursuit of long life, high quality and reliability. The increase in service life of automotive wheel bearings, by improving the rolling contact fatigue (RCF) life of bearing steels, was investigated. Conventional studies of bearing steels and heat treatments have dealt with quenching and tempering (Q/T) in 52100 steel. This study is a new trial to increase the strength of bearing steels by special austempering in phases after general Q/T heat treatments.

Developing a brake system with high overall customer satisfaction rating is a constant challenge for OEMs as well as their brake suppliers. Brake system performance is directly linked to the engagement between the rotor and pads. The materials for the rotors and pads play a key role in the nature of the engagement. Therefore, it is critical to have a good understanding of brake rotor materials to meet performance targets. Due to its superior thermal handling capacity, damping characteristics, wear and cost advantages, gray iron is the most widely used brake rotor material in the industry. G30 per ASTM A48 is generally specified for most brake rotors with minimum tensile strength of 200 Mpa and Brinell hardness of 187~241. G20 is also widely used for brake rotors, especially when people are looking for brake smoothness and optimal pad life. This study has found that variation in gray iron material can considerably affect brake output, wear, DTV, BTV, and noise propensity.

Abstract The lifting and excavating industry are not as advanced as automotive in the use of modern CAE tools in the early stages of design and development of heavy machinery. There is still a lack of confidence in the integrity of the results from FE simulations and optimisation and this becomes a barrier to the adoption of virtual prototyping for vehicle verification. R&D of Tata Steel has performed tests on two forklift truck overhead guards supplied by a major manufacturer. Based on the international standard for Falling Object Protective Structures (FOPS) as an initial input to the method of testing, the main aim of this study was to generate as much test data as possible to correlate the Finite Element (FE) simulations of two tests - a static and a dynamic test. The static test was developed to deform the overhead guard plastically in a slow controlled manner, so it would be easier to correlate the measured data to FE simulation.
