Abstract
More and more automotive companies realize that controlling the tribological conditions in stamping production enables prevention of production issues, increasing overall production stability, and therewith achieving higher quality parts. Therefore, increasing effort is spent in accurately accounting for friction and lubrication conditions in sheet metal forming simulations. In this work, a selection of results for a Groupe Renault case is presented whereby forming simulations are utilized to simulate issues, including splits and wrinkles, observed in stamping production for the Renault Talisman trunk lid inner part. A comparison between simulation results and experimental measurements on parts taken from production is made. This comparison shows that the respective issues can only be simulated accurately when accounting for the actual tribological conditions in stamping production. By doing so, simulation accuracy is increased, now enabling Renault to improve part quality by controlling, adjusting and optimizing the tribological conditions in both in simulations and production.
