Models
For over a decade, we have been developing finite element (FE) models for use with Ansys LS-DYNA and the Oasys Suite. We have produced a range of barrier and pedestrian impactor models in collaboration with Cellbond. We also distribute various dummy models including THUMS, GHBMC, FAT, etc. which can be accurately positioned, quickly and easily with Oasys PRIMER positioning trees.
Arup RCAR Barrier Model
Thatcham, the IIHS, and other insurance groups around the world carry out low speed bumper impacts to assess the reparability of different cars. Arup have developed an FE model of the RCAR bumper, the main barrier used in these tests.
To help users quickly identify the latest FE model versions and their corresponding regulations, we’ve introduced this summary table. It provides a clear reference point for engineers to see which barriers are available, which regulations they align with, and what version is currently supported. Each barrier name links to its individual model page for further detail.
