This means that during the production stages, an alternative material vehicle will load the environment with significantly more GHG emissions than that of a steel vehicle. On this chart, using the University of California LCA comparison model, we show an Advanced High Strength Steel vehicle (represented by the red line) and an aluminium vehicle (represented by the blue line). Notice that the steel vehicle creates slightly more GHG during the vehicle use phase, however, the aluminium vehicle releases a significantly higher level of GHG emissions during the material & production phase. It seems logical enough then that auto companies would embrace an LCA approach. However, many existing or proposed government-driven regulations address the use phase only. Use-phase only regulations can lead auto manufacturers to select GHG intensive materials that may improve the use phase but increase the total life cycle greenhouse gasses. In other words – leading to unintended consequences or wrong choices from the planet’s point of view.
Our experts work with our customers in the press shop on a daily basis, helping and advising, and also in the body assembly area, providing advice and support on joining and weld line set up. Over the last few years, this close working relationship has led to some real breakthroughs in Press Shop technological support and I will describe a couple of these now.
A unique and portable strain measurement system called PHAST , has been developed by Corus, the international steel company, to help carmakers ensure reliable production quality of complex formed body panels during the vehicle development and production process. Combining hardware and software, the PHAST system has been jointly developed by Corus and Geodelta, a global leader in photogrammetry. Unlike similar systems in the market, PHAST is the first that combines expertise in 3D measurement technology with materials knowledge. Using PHAST involves photographing a pressed panel from different positions using a digital camera and then processing the data. The software is capable of linking all the photographic measurements automatically, calculating the strains in the pressed part with an accuracy of ± 0.5 per cent strain. The results are typically available within 1-3 hours, and are used to make often minor changes to the press tools to help avoid subsequent problems in volume production. The PHAST system has successfully been used by Corus to provide critical on-site body shop support to Ford’s Genk manufacturing plant, helping the carmaker to save valuable time, cut costs and ensure consistency in quality.
Our Aurora materials database is accessible to our customers automotive engineers through our weblink, containing material property data for 10 Euronorm and 5 specific Corus grades of steel. It is a single and consistent source of data, not only for customers, but also our internal data sharing needs. New for 2007 are ready to run input decks for Autoform, PAM-STAMP and PAM-CRASH, with further codes in development. For the forming decks, data is included for the low, average and high end of the forming window, allowing variability studies and higher confidence in the robustness of the analysis.
