Abstract
Introduction (problem statement and relevance). The studies aimed at vehicle passive safety improvement have been conducted since the middle of the 20th century. In order to determine the consequences of road accidents, anthropomorphous testing devices – dummies – are used. Besides actual or field testing for vehicle design preliminary assessment, virtual testing implemented by means of the finite-element method is conducted. The issue of development of the dummies finite-element models showing physical behavior and high accuracy of the results obtained at simulation is relevant for the domestic automotive industry development, since only free of charge models, which do not comply with the specified requirements, are available to the engineers at this time.
The purpose of the study is description of the phased plan to form the procedure of dummy finite-element model development.
Methodology and methods. The papers devoted to development of the dummies and their mathematical models and development of the dummies models and their validation have been reviewed.
Scientific novelty and results. The paper shows the basic issues arising at virtual testing simulation using the dummies. The scientific novelty consists in justification of necessity to arrange a domestic study to perform vehicle virtual testing for passive safety.
Practical significance. Considering the issue specified in this paper, studies aimed at development of domestic finite-element models of the dummies can be conducted.
