Abstract
The article analyzes the approaches to the creation of the concept of a virtual test bench for testing the digital twin of the automotive industry product. Such components of the digital platform as suspension area, power plant, braking and cooling systems are being investigated. The problem of the implementation in the digital twin of such important units as the attachment points of units and assemblies on the vehicle body frame, even surface, driver dummy, the scheme of attachment of body elements, etc is studied. The importance of the implementation of such benches as platforms for assessing the indicators of the vehicle passive safety or as stand for assessing the water tightness of the vehicle body is considered. A number of results that illustrate development areas and success of the authors of the article in these areas are presented. It is shown that the digital platform can be used for certification and rating tests, assessing the comfort and visibility of the driver's cab.
Highlights
The current level of development of digital technologies has made it possible to create systems for the design of complex technical products based on the so-called digital twins
- Stand for assessing passive safety indicators in frontal impact; - Stand for assessing passive safety indicators in a side impact; - Stand for assessing passive safety indicators in a rear impact; - Stand for assessing passive safety indicators during a vehicle rollover; - Stand for assessing the indicators of aerodynamic resistance and downforce; - Stand for assessing the kinematic properties of the suspension; - Stand for the assessment of vibroacoustic comfort; - Stand for assessing the stiffness and strength properties
The article demonstrates the results of the development of a digital platform for testing and assessing the digital twin parameters of an automotive product
Summary
The current level of development of digital technologies has made it possible to create systems for the design of complex technical products based on the so-called digital twins. The main idea in this approach is the use of a mathematical model of the developed product, which provides sufficient accuracy in calculating certain parameters of the product. Virtual platforms and stands began to appear. It allows testing a product with imitation of specified conditions, modes, testing parameters, etc. It is obvious that such a combination of modeling, evaluation and subsequent optimization of product parameters makes it possible to create systems for automatic product optimization. The adequacy of the assessments obtained with the help of such stands is determined by the accuracy of the mathematical model and the methods of numerical calculations
