A vehicle damage resistance assessment method based on digital twin

Abstract

The invention discloses a vehicle anti-damage evaluation method based on digital twins. Firstly, the physical vehicle is digitally twinned, and a digital twin model with high simulation performance is established. This model includes four major systems: virtual vehicle firmware system, dynamic Real-time interaction system, external information interaction system, and vehicle status monitoring system. On this basis, the vehicle damage subsystem is constructed through external services, and digital vehicles are simulated to attack. The vehicle status monitoring system is supplemented by various methods to attack The effect of damage is evaluated to obtain the anti-damage evaluation data of the vehicle, and the anti-damage evaluation of the vehicle is carried out.

Description

technical field [0001] The invention relates to a digital twin and a vehicle damage assessment method based on a Bayesian network and an image, in particular to a vehicle damage resistance assessment method based on a digital twin technology. Background technique [0002] Digital twin technology is a way to reflect the physical entity into the digital model through digital modeling, so as to realize and maintain a high degree of consistency between the physical entity and the virtual digital model. By reflecting the physical entity to the digital model, various high-simulation operations on the model can be realized in the digital field, avoiding the disadvantages of difficulty and high cost when operating the physical entity. Digital twin technology combines modern multiple disciplines at the same time , is a nascent and dynamic technology. [0003] Because the digital twin of a physical entity involves multiple disciplines such as physics, informatics, and materials scien...
