Abstract

The invention discloses a vehicle damage resistance evaluation method based on digital twinning. The vehicle damage resistance evaluation method includes the steps: firstly, digitalized twinning is carried out on a physical vehicle; a digital twinning model with high simulation is established; and the model comprises four systems, namely, a virtual vehicle firmware system, a dynamic real-time interaction system, an external information interaction system and a vehicle state monitoring system. On the basis, a damage subsystem of the vehicle is constructed through external services, and simulation attack is conducted on the digital vehicle, and the damage effect is evaluated through a vehicle state monitoring system and various methods, so that damage resistance evaluation data of the vehicle are obtained, and damage resistance evaluation is conducted on the vehicle.

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...
