Abstract

The article presents the results of the implementation of work in the field of creating virtual test benches for testing vehicle passive safety in the event of an impact. A number of results obtained on the basis of implemented virtual platforms and benches are given. The advanced technologies in the field of creating virtual benches and digital twins are also shown. The illustrations on the problems of testing A-pillars and the vehicle roof, including the cases of a frontal impact are given. Certain considerations are given on the general concept of digital design based on digital twins and virtual test benches. The critical impact on the adequacy of the digital twin and the benches and platforms built on its basis is highlighted. The accuracy and convergence of the mathematical model of the designed product and the physical processes occurring in it, the used numerical methods of computer simulation, finite element models and their optimization is pointed out.

Summary

Introduction

One of the most important tests for a designed vehicle is a crash test. It is an assessment of the passive safety of passengers and the driver in a frontal, rear or side impact, as well as during a vehicle rollover. Are the results obtained on the designed virtual platform, which is built on the basis of the digital twin of a vehicle. This approach allows the assessment and optimization of a number of parameters to be realized at a new level. Working with the digital twin of the designed product provides an opportunity to consider the smallest details, which at the same time have a significant impact on the level of compliance with the requirements of international standards for vehicle safety, etc
