ABSTRACT: In this paper, co-simulation between a concept beam and a flexible body is studied, with the purpose to increase computational efficiency for crash simulations. The behaviour of a simple beam during a longitudinal impact with a wall is presented. The simple beam is modelled by two parts: a 1D model created with LMS Imagine.Lab AMESim and a 3D model created with LMS Virtual.Lab Motion. In order to obtain reference results, the impact behaviour of both a finite element simple beam using LSTC LS-Dyna and a concept beam modelled in LMS Imagine.Lab AMESim are considered. The co-simulation-based results validate well with the two reference results.
