Digital twin system design for dual-manipulator cooperation unit

A measurement of designing virtual models based on physical entities is helpful for many companies to design their own virtual workshop models for workshop production scheduling and optimization, but a single virtual workshop model cannot reflect the interaction of physical and information objects required for intelligent manufacturing. However, the digital twin workshop is an effective approach to reflect the combination of virtual and physical then to optimize the operation of the workshop production. This study, focusing on the definition and role of digital twin engines in a digital twin workshop, researches on the concept of digital twin workshop, and takes the dual-manipulator cooperation production unit as an example to verify the proposed method for constructing the digital twin workshop.

I. Introduction

Virtual workshop models are widely applied by different companies in scenarios such as workshop scheduling and simulation optimization. Typical applications include machining simulation, assembly simulation, logistics simulation, and plant layout simulation. Through virtual simulation, the key link in each stage of the life cycle of the workshop can be previewed, problems in the design can be found in advance, and changes in the design scheme during the construction process can be reduced. However, the single virtual workshop model cannot reflect the characteristics of the interaction and fusion of the physical and information worlds required by intelligent manufacturing. One of the key points emphasized by digital twin technology is the connection between the physical and virtual worlds for realizing the unification of the virtual and the real world. Achieve a closed loop between production and design. Therefore, the digital twin technology is an effective way to realize the virtual and reality combination and intelligent optimization management in digital twin workshop.
