Abstract

According to the self-adaptive adjustment method and system based on the digital twinborn body, a line laser sensor and a camera are used for carrying out digital measurement on the outline and end face positioning pin of a cylindrical assembly body, and the axis of the cylindrical assembly body and the axis of a pin hole are fitted out; by adjusting the position of the cylindrical assembly body,the axes of the assembly body are controlled to be consistent, and self-adaptive assembly and adjustment are achieved based on digital twinning body virtual monitoring. Techniques by means of digitaltwinning, an assembly analog simulation environment based on virtual-real fusion is constructed; the manufacturing system Internet of Things serves as a carrier, interconnection and intercommunicationbetween the physical world and the information world in the assembling process are achieved, and through virtual-real mapping and information interaction based on real-time data, precise simulation,monitoring, diagnosis, prediction and control over the states and behaviors of aerospace precise complex product parts, equipment and the assembling process are achieved.

Description

technical field [0001] The invention relates to an adaptive adjustment method and system based on a digital twin. The method and system have the characteristics of intelligence and practicality, and can effectively solve the technical problems of "imitation without realism" and low assembly and adjustment efficiency existing in traditional assembly simulation. Background technique [0002] With the in-depth advancement of full 3D manufacturing and the rapid response to manufacturing needs of aerospace precision and complex products in a short period of time, the problem of "imitation but not real" in traditional assembly simulation has seriously restricted the improvement of assembly efficiency and first-time assembly pass rate. The key issues involved include rapid modeling of physical products at the assembly site, assemblability prediction of precision products under complex working conditions, adaptive closed-loop control of assembly process under multiple constraints, e...
