FEA Simulation and Probability Approach of the Road Barrier Crash Tests

Popis výsledku v původním jazyce

The design and verification of the new types of road safety barriers suffers from several deficiencies including a lack of prescriptive models for impact forces caused by various types of road vehicles. When designing the load-bearing members of barriers, alternative procedures for accidental actions,including dynamic ones, non-linear and probabilistic approaches are applied. Detailed analysis of the crash behaviour of road restraint system is based on non-linear dynamic finite element simulations using vehicle models. Modelling process is validated with the real tests in collaboration with the testing laboratory TÜV SÜD GmbH in Memmingen. Main project aim is to develop accurate methodology that would replace the real crash tests into traffic barriers with numerical simulations and reliability methods. In spite of improvement of CAE engineering and numerical simulations methods, the certification and homologation based only on numerical methods is not anticipated in a near future. Main aim is to reduce number of the physical tests and substitute them with simulations. Such an approach would significantly reduce costs for any road safety system development with only one physical homologation test.
