Abstract:
With the popularization and application of 5G technology, everything is connected and the future can obtain more capabilities. Digital twin will bring revolutionary changes in design, production and maintenance of manufacturing industry. The market demand of manufacturing industry is changing from batch to customization, from single to multi variety, from long cycle to fast update, from popularization to high-end. As a result, intelligent technology should be used to meet the market demand and solve the manufacturing problems. Digital twin, the key intelligent technology, will bring revolutionary changes to the manufacturing industry. The so-called digital twin is to integrate multi-disciplinary, multi-scale, multi probability simulation process by using physical model, sensor update, operation history and other data to complete mapping from real space to virtual space. Digital twinning is not only replication, but also mapping various attributes of physical devices into virtual space. The application and development advantages of digital twin technology in intelligent manufacturing are illustrated by NASA aircraft health management, Siemens Amberg digital plant and industrial Internet platform of the General Motors Company. The virtual assembly of automobile engine supported by digital twin technology can not only move, see the changes in the operation of internal parts and joints, but also work out the speed curve to see whether it meets the actual needs of the enterprises.
