Computer Modelling

In parallel to its experimental activities, L.I.E.R. has acquired significant experience in the computer modelling of crash tests on road safety systems.

With its significant experience and expertise in the field of road safety system testing, the laboratory has an incomparable experimental validation resources for the development of reliable computer models.

L.I.E.R. offers to its clients different types of studies depending on their objectives.
It can be either the development of new road devices or the modification of existing devices. In both cases, L.I.E.R. has to perform in-depth studies using optimisation techniques.

The hub of the system used for simulation is the finite-element explicit calculation solver (Ls-Dyna®) which is complemented by the programs needed to create models of all types of system and all types of material.

Furthermore, L.I.E.R. has at its disposal a library of vehicle models and a bespoke tool, the BarrLier software which aids creation of data and the analysis of experimental design results and which refers directly to the impact conditions defined by the European standard EN1317.
