Digital twin-based virtual reality experiment system for a hydraulic circuit
[Objective]This immersive digital twin-based virtual reality(VR)experiment system for hydraulic circuits integrates real-world physical structures with a twin model in virtual space,which significantly facilitates the researcher's in-depth understanding of the operation process and basic principles of the hydraulic system.To improve understanding of the application of digital twin technology in intelligent manufacturing processes and the demand for practical training of digital twins for cultivating new engineering talents,this study explores the application of digital twin technology in engineering education.This also has the potential to enhance students'understanding of the principles of hydraulic systems and practical operation capacity.The digital twin system developed herein provides a safe,controllable,and highly interactive learning environment for learners by generating accurate virtual twin models of physical entities and synchronizing data in real time.[Methods]The distributed digital twin system architecture proposed herein consists of four key components:data sensing,cloud services,the twin model,and VR mapping.This architecture enables efficient simulation and real-time interaction with the hydraulic system,providing a comprehensive and intuitive learning platform for learners.The data sensing component monitors various physical quantities related to the hydraulic throttling speed control circuit in real time through a series of sensors that measure indicators,such as the pressure,flow,and displacement of hydraulic cylinder rods.These sensors then send these data to the cloud service platform using wireless transmission technology.The cloud service component acts as the data processing and management center of the system and is responsible for storing a large amount of data from the data sensing component and providing data subscription and distribution services.The twin model visualization component is the core of the system,and it can construct a highly realistic 3D digital twin model of the hydraulic throttling speed control circuit using Unity3D software and C#script.The VR mapping component facilitates data synchronization and interactive control between the virtual model and the physical entity by establishing a communication bridge between the computer terminal and the physical entity of the hydraulic system.[Results]To verify the effectiveness and practicality of the proposed digital twin-based hydraulic circuit virtual experimental system,a series of experimental construction and validation tasks for the hydraulic circuit were conducted.The experimental validation showed that the constructed digital twin system can accurately simulate the working principle of the hydraulic circuit and provide rich interactive functions for students to more intuitively understand the hydraulic circuit.Using VR mapping technology,the learner's operations in the virtual experimental environment can be fed back into the real experimental platform in real time,achieving a seamless connection between the virtual environment and the real environment.[Conclusions]The immersive digital twin-based VR experiment system for hydraulic circuits not only improves teaching efficiency and expands the perspective of hydraulic technology education but also enhances students'understanding of new digital twin engineering technologies and provides learners with a new learning perspective and tools.While improving students'understanding of hydraulic circuit principles,this system also exercises students'ability to solve practical engineering problems,stimulates their interest in the field of hydraulic technology,and provides new ideas and methods for innovation and progress in engineering education.
