Finite element modelling of pedestrial upper legform impactor used in automotive safety testing

Abstract

    Pedestrian safety testing when a collision occurs is a mandatory requirement for all cars sold in the European Union. European Enhanced Vehicle-Safety Committee (EEVC) tests the safety of cars by impact to models that simulate pedestrian body parts including headform impactor, upper legform impactor and legform impactor. These three parts are often injured when pedestrians impact to cars. These models are designed so that dynamic properties of impactors similar to impact to the corresponding parts of the human body in car collisions. Collision with the upper legform impactor is one of the mandatory requirement testing. Currently, many cars are developed to protect pedestrians in collisions. Developing process need to perform many tests of upper legform impactor to car collisions, these tests cost a lot of time and money. In this study, the upper legform impactor which is used by EEVC in pedestrian safety testing will be finite element modelling. This model and finite element modelling of cars will be used to perform the the collision by computer. This will help to save much time and money in process of development cars.
