Driving Innovation through Multidisciplinary Optimization

Jerome Lagrut, Cab Analysis - Geometrical Assurance - Metrology - Volvo 3P

How can we reduce lead time and product development cost while increasing quality level? One of the solutions is to integrate CAE optimization in early phases and all along the projects. Topology and shape optimization are helping the designers to find the right shape for the parts based on load cases and manufacturing constrains. Design Of Experiments are scanning all the possible variations of a system to understand how the changes are influencing results, a good way to isolate the best solutions.

The challenge we are now facing is to combine different CAE domains (crash, durability and NVH) to run multidisciplinary optimizations covering a larger spectrum of possibilities. As a first test of multidisciplinary optimization, we set up an important design of experiment using the Altair products (HyperMesh, HyperStudy) with a target of BIW spot weld reduction.

The conclusions of this optimization are very rich and opening many possibilities of product cost reductions.

Jerome Lagrut graduated in mechanical engineering from the Université de Technology de Compiègne in 1999.

From 1999 to 2004, he worked for Mecalog where he developed his knowledge in crash simulations using RADIOSS. He also had the opportunity to work for several car manufacturers around the world: PSA Peugeot Citroen, Ford, Honda, Ferrari.

In 2005 he started to work for the Volvo Group as a CAE crash specialist. Based in Lyon, at the Renault Trucks center, he is now the CAE group leader for the cab department where crash, durability, CFD and NVH analysis is made. He is also in charge of the geometrical assurance and 3D metrology group.
