摘要：
To solve the problems of low assembly efficiency and poor consistency of assembly quality caused by disconnection between virtual simulation analysis and physical assembly in assembly process of high precision products, an intelligent assembly method of high precision product driven by digital twin was proposed. The digital twins of high-precision products including all assembly elements were constructed. Aiming at the problems of poor readability of assembly process documents and weak knowledge correlation, an assembly process expression method based on knowledge map was proposed. At the same time, the dynamic adjustment of assembly process was realized by using the inferential property of knowledge map. Aiming at the problem of product quality control, a three-layer structure quality control strategy of operation-state-quality was proposed. Taking the assembly of a certain type of automobile engine block unit as an example, the practicability of the proposed method was verified. © 2022 CIMS. All rights reserved.
