Abstract

In the early phase of vehicle development, car manufacturers need to ensure the compliance with strict safety requirements while facing the problem of low data availability. Aiming to support the engineers, we propose a transfer learning (TL) framework for crashworthiness. The design of the new product can be viewed as a broad modification of past ones. For this reason, an attractive concept to investigate is the development of a machine learning (ML) approach able to learn from past designs, transferring the acquired knowledge to the new ones. TL can serve to this aim. Here, we propose a TL framework and apply it to explicatory industrial crash examples. To allow the ML model to learn the topological differences between old and new designs, we propose two approaches: sphere projection- and PointNN- based TL. Both approaches enhance TL, which results in a powerful technique to extract valuable information from limited datasets.
