Analysis of the degree of impact of passive safety system active elements of passenger cars on driver’s pole side impact injuring
EDN: CFHYFU
Abstract
Introduction (problem statement and relevance). Increasing the level of vehicle passive safety remains one of the priority tasks of the modern automotive industry despite the continuous improvement of designs and systems. It is particularly difficult to ensure protection of the driver in case of side or lateral collisions, which, having a relatively low probability of occurrence, are characterized by extremely severe consequences due to the minimum area of absorption of impact energy. In such conditions, human safety depends in many respects on operational efficiency of passive safety system active elements (seat belt and side airbags).
The purpose of the study is to assess the degree of impact of passive safety system active elements on the index or indicator (total score) of passive safety of a passenger car.
Methodology and research methods. In order to conduct virtual testing, a comprehensive numerical modelling approach is used. The finite element method is used to reproduce the process of vehicle body deformation at the pole side impact as well as to analyze the anthropomorphic dummy interaction with the vehicle interior elements and the seat belt. The corpuscular particle method is used for high-precision modelling of the process of side airbags gas filling and interaction with the dummy.
The scientific novelty and results lie in development of a point rating system assessing the passive safety according to a set of the pole side impact injury criteria established by UN Regulation No. 135 and in assessment of each passive safety element contribution to reducing driver’s pole side impact injuring.
The practical significance consists in creation of a tool (point rating system) for quantitative assessment of passive safety at a pole side impact, which allows aligning different injury criteria into a single integral index for comprehensive assessment of driver injuring.
