Summary:

An automobile is designed to meet numerous impact events,including frontal impact, side impact, rear impact, and roll over.Roof crush resistance is a test defined by Federal Motor VehicleSafety Standard (FMVSS) 216. The intent of this test is to evaluatethe strength of the roof and supporting body structure during avehicle rollover. Steel countermeasures are typically used asstructural-reinforcing elements to the body structure to improvethe crush strength of a vehicle roof.This paper presents a thermoplastic countermeasure (CM) designas a light-weight solution to replace traditional steelcountermeasures. Two concepts are discussed in the paper: anall-plastic countermeasure and a plastic/metal hybridcountermeasure consisting of stamped steel with a thermoplasticreinforcing rib structure. Finite Element (FE) methods usingLS-DYNA are used to evaluate the performance of thesecountermeasure concepts. A generic Finite Element model of a sportutility vehicle is used in the analysis. The countermeasureconcepts are assembled inside the B-Pillar and the crush strengthof the roof is evaluated as per FMVSS-216. This study shows thatthe thermoplastic countermeasure can be developed with similarstiffness and strength as steel countermeasure, yet with ~40-50%mass savings. This paper provides an overview of the performancefor the thermoplastic countermeasures
