Abstract

 
 
 
 This work follows up the previous work [1] regarding the used methodology in the field of passive safety, ie. crash testing. The work is based on experience gained in the Active Lateral Impact Simulator (ALIS) project and describes complete process. The main focus has been given to the fine-tuning of the boundary conditions and loading of the system in order to ensure correct biomechanical loads.
 
 
 
Highlights
This work proposes a new advanced approach of combined virtual and physical testing
The main reason of the virtual experiments is to perform sensitivity analyses that would later give a good knowledge of the system behaviour. This is useful during the physical testing, when quick response to the current behaviour and recommendation of the steps is highly expected and there is no time for further simulations
For illustration there is a comparison of initial Active Lateral Impact Simulator (ALIS) run, with all variables equal to 1, and full crash model shown on Figure 6
Summary
This work proposes a new advanced approach of combined virtual and physical testing. The main idea is to reduce development time and associated costs by using sled testing which used to be used mainly for physical simulation of frontal crashes. Simulation of side crash in sled environment is not a brand-new topic, but certainly very complex one. This method is not really used on regular basis especially due to predictability issues and low accuracy. This work presents new approach of combination both virtual and physical testing. The whole process starts with full crash simulation, goes through conversion of virtual model to reduced sled model, sled testing and is wrapped up with full vehicle crash
