Prediction of Squeak & Rattle for robust product and production

Project time: 2015 – 2017

Budget: 6 592 000 SEK

Funding: SIP Produktion2030

Purpose and goal

The project has met the aim of improving the ability to predict S&R during development phases of an industrial development project. The principle has been that a robust product that is insensitive to interferences that can create S&R w ill provide robust production where late detected S&R problems are minimized. All w ork packages defined have been conducted w ith good results. In addition, tw o out of three w ork packages have opened-up new research questions that w ill further push the development of new prediction methods

Results and expected effects

The project has used different methods to improve the capability of S & R simulations. The area is by nature multidisciplinary, since the mechanisms for S&R are many and are found in different simulation disciplines. Contributing results are generated in all completed w ork packages through softw are integration modal transient analysis and tolerance analysis, reduction of iteration steps in simulation through development of a single load case replacing multiple load cases for different test tracks and finally refinements in simulation methods for S&R prediction.

Tailored Tool Surfaces for Robust and Sustainable Hot Stamping

Tooling constitutes a significant part in the economical investment of the hot stamping process. Significant benefits in production economy and environmental benefits can be attained by improving the tribological performance in hot forming operations of automotive components. The main idea of this project is to create tailored tool surfaces on dies made from cheaper and easier to manufacture tool steel for the hot stamping of ultra-high strength steels.

PADOK – Study Visit to India 2016

With globalization and other megatrends as demographic changes and climate change, more knowledge is needed regarding production in an international perspective. PADOK Study Visit in India 2016 have given an increased knowledge regarding how production is conducted in India, some of the challenges producing companies in that region is facing and how Swedish companies interested in investing in production in India could act to establish themselves in the region.
