This technical report is part of the work that is performed under a MERA project, L-FAM II. Between 2006 and 2008 this was a part of a research project between Volvo AB, VINNOVA, Flex Prop AB, Halmstad University and Lund University. L-FAM II was the name of the project and it was to help the industry to facilitate flexible lifting aids for their chassis-building. Criterion is an important part in this project since some of those controls with the accuracy of the finished product will receive. This accuracy is reflected immediately when the product goes into production where it must secure the geometry of products for the welding of body components and cabins.
In this project, carbon fiber materials have been an important part. The advantage of carbon fiber is its low weight in relation to its stiffness. The cost of the material is not in its favor.
The lifting devices that means here are constructed based on these criteria and are already in production. The system has been named NBT2 and is a patented solution in which ABB is the owner of the patent. The patent describes the method and process of how NBT2 is constructed and are described more in paten document No. WO 01/94191 A1.
20 different criteria have been developed which have also been approved by the project stakeholders. A survey was done early in the project where we consulted a number of people who have good insight into the product. The criteria are only part of the work of what WP1 will perform where the goal is a completed computer-based design systems. The report includes a description of what this computer based design system will perform. The various digital tools and utilities that will be used are explained in the report.
There are still information missing from the rest of the WP inside the project which has force Wp1 to perform a series of tensile tests where the goal is to find a template for how to use materials from product geometric design. The goal is that this computer-based design system should be ready in late 2010.
