What do you mean by digital twins?

Digital pairing is to make full use of data such as physical model, sensor update and operation history. In order to integrate the multi-disciplinary, multi-physical, multi-scale and multi-probability simulation process and complete the mapping in the virtual space, thus reflecting the whole life cycle process of the corresponding physical equipment.

Digital twinning is a concept beyond reality, which can be regarded as a digital mapping system of one or more important and interdependent equipment systems. Digital twinning is a general theoretical and technical system, which can be applied in many fields, especially in product design, product manufacturing, medical analysis, engineering construction and so on.

The most in-depth application in China is the field of engineering construction, and the most concerned and popular research is the field of intelligent manufacturing. Digital pairing is sometimes used to refer to the digital model of factory buildings and production lines completed before construction. So as to simulate the simulation factory in the virtual network space and transmit the real parameters to the actual factory construction.

After the workshop and production line are completed, information will continue to be exchanged in daily operation and maintenance. It is worth noting that Digital Twin is not a tool for configuration management, nor a 3D model of finished products, nor an MBD definition of finished products.

The extreme demand for Digital Twin will also promote the development of new materials, and all anomalies that may affect the working state of equipment will be clearly investigated, evaluated and monitored. Digital Twin integrates sensor data, historical maintenance data and related derivative data mined from the embedded integrated health management system (IVHM).

The significance of digital pairing

The most important enlightening significance of digital twinning is that it realizes the feedback of the real physical system to the digital model of cyberspace. This is a feat of reverse thinking in the industrial field. People try to cram everything that happens in the real world into digital space. Only the life cycle tracking with circular feedback is the real life cycle concept.

Only in this way can the harmony between digital and physical world be truly guaranteed in the whole life cycle. The application of all kinds of simulation, analysis, data accumulation, mining and even artificial intelligence based on digital model can ensure its applicability to real physical systems. This is the significance of digital twins to intelligent manufacturing. ?
