Abstract: Amid the emergence of Industry 4.0 and intelligent manufacturing, digital twin technology has garnered significant attention and undergone swift advancement. This paper presents a design framework for digital twins, along with a conceptual modeling approach tailored to this technology. The proposed digital twin design architecture is anchored in the 3D model, offering a comprehensive elaboration of the bidirectional mapping relationship between the target object, pertinent data, and the model. Additionally, it delves into the evolutionary trajectory of the digital twin. Lever-aging the object-process methodology, this study extends the attributes of objects and processes, ultimately formu-lating the minimal general ontology for digital twins. To illustrate our approach, we employ the unmanned aerial ve-hicle electric propulsion system as a case study. Through this lens, we establish a conceptual model of the system, providing an in-depth account of its composition, behavior, and performance. The outcomes obtained are promising.
