Abstract

A finite element (FE) model of a convertible forward-facing child restraint system (CRS), presented previously was combined with a Hybrid III 3-year-old dummy model and an ECE44R test bench model. The combination will replicate the last ISO proposal for side impact tests of CRS in order to analyze the influence of the longitudinal acceleration pulse seen during FMVSS 214 tests. This influence is shown to be limited, as long as the dummy is confined within the CRS shell. In agreement with previous crash investigations, the simulated intruding door in the ISO proposal is responsible for a large share of the loads acting on the child dummy. The validation of the virtual model and limitations of the child dummy FE model are discussed. Simulation results are compared with an actual frontal test using the same CRS model. For the covering abstract see ITRD E825082.
