| Abstract: | The acceleration Severity Index (ASI), described in European Standard EN12767 (The passive safety of support structures for road equipment. Requirements, classification and the test method) is regarded as the most important indicator of impact on the occupants. The requirements for experiments are described, having in mind that the results depend on many factors. One of them is the selection of a vehicle to be used in the crash test. To perform numerical vehicle crash simulation, the finite-element models of permanent road equipment support structures were developed using the LS Dyna software available. To examine the response of the vehicle upon the impact, the acceleration severity index curves were calculated and visualised in Matlab. |
