Virtual reality technology is an important emerging information technology. It has a bright prospect of integration with manufacturing industry and is expected to become a new tool and a new impetus for innovating the development mode of manufacturing industry and enhancing the competitiveness of manufacturing industry in the future. To promote the strategy of building a powerful nation and achieve the transformation and upgrading of the manufacturing industry can not be separated from the application of a new generation of information technology. The emergence and development of virtual reality technology have provided new tools and new methods for the innovation and development of the R & D, manufacturing, management, sales and service of the entire industrial chain in the manufacturing industry, and have also brought a new starting point and a new approach for the in-depth integration of the two industries power. With the common development of virtual reality technology and industry, manufacturing virtual reality technology applications continue to emerge, with China First Tractor Group Co., Ltd. (YTO Group for short), for example, the company applied the local company Mann constant digital research and development of " Digital virtual reality display system "to create a virtual assembly shop, 360-degree panoramic view of the roaming can be achieved for China's large-scale agricultural equipment manufacturing industry has injected new blood and strong force. China must seize the opportunity and step up the promotion of this technology to help the manufacturing industry to transform and upgrade in the direction of digitization, networking and intelligence. Virtual reality technology has broad application prospects Virtual reality technology can show the three-dimensional appearance of the product, so that developers can conceive all aspects of the product shape, structure, mold and parts and components to use the program. Especially in the development of large equipment products such as aircraft and automobiles, the use of virtual reality technology can greatly enhance the accuracy of aerodynamics and product performance. Boeing Co., Ltd. applied virtual reality technology to the design of the 777 and 787 aircraft. Through the virtual reality projection and motion capture technology, it completed the design of the aircraft's appearance, structure and performance, and the deviation between the obtained solution and the actual aircraft Less than one thousandth of an inch. According to statistics, the Boeing 777 aircraft designed with virtual reality technology has a 90% reduction in design error modification, a 50% reduction in research and development cycles, and a 60% cost reduction. At the assembly stage, the virtual reality technology is currently mainly used in the field of precision machining and large equipment manufacturing. Through the combination of high precision equipment, precision measurement, precision servo system and virtual reality technology, the virtual and real technology can realize the material uniformity, Shockproof processing environment, as well as the system error and random errors of the processing system with the precise coordination between, so as to improve equipment efficiency and quality. YTO Group applied the digitized virtual reality display system developed by the local company Mann Digital to create a virtual assembly shop capable of 360-degree internal panoramic roaming, which can not only observe each assembly station from multiple angles but also precisely track assembly workpieces The production process for our country's large-scale agricultural equipment manufacturing industry has injected new blood and a strong force. Virtual reality technology used in complex system maintenance work, to be able to achieve from the factory to the sale of the whole process of testing, and break through the space constraints, shorten the time needed to improve service efficiency, expand service content and improve service quality, manufacturing services To push the new stage. For example, Ford Motor Co. and Chrysler Co., Ltd. jointly developed with IBM to develop a virtual reality environment for automobile manufacturing to verify their existing design defects and assist in the modification and greatly shorten the development cycle of a new car. In the future, through remote data transmission, virtual reality technology will help enable real-time, remote and predictive monitoring and repair services. The use of virtual reality training in complex, high-precision manufacturing environments enables the stereotyping of manufacturing scenarios to help participants gain a highly simulated, repeatable and low-risk manufacturing process learning experience with a full range of perceptual experience. Similar to the aviation industry's experience of using virtual reality technology to simulate cab training astronauts, the use of virtual reality technology to establish a virtual training base is conducive to familiarizing manufacturing practitioners with manufacturing scenarios and enhancing application skills. At present, many domestic and foreign enterprises have used virtual reality technology to carry out training. For example, the British Royal Armored Company uses virtual reality technology to simulate new 14.5-tonne vehicles and train operators in specialized vehicles. Opportunities and challenges co-exist From the perspective of application, China has formed a number of scientific research achievements in the field of virtual reality, laying the foundation for the promotion and application of manufacturing industry. Beijing University of Aeronautics and FAW jointly developed sheet metal forming software can basically simulate the door and other complex cover stamping process; ESR casting simulation software developed by Shenyang Institute of Foundry has been used in turbine blade surface modeling; Hefei University of Technology developed a double-turret CNC machining simulation has been applied to Ma On Shan steel wheels wheel hoop factory. From application practice, China has initially applied virtual reality technology in the fields of high-end manufacturing such as aerospace, aviation and automobile. China Commercial Aircraft developed a virtual reality simulation system for advanced research and assessment of key new civil aircraft and key technology research. FAW, SAIC, SAIC and other automotive companies using UG, CATIA, PRO-E and other three-dimensional software product design has accumulated for many years Experience, with the data foundation needed to apply virtual reality. Judging from the industrial base, China ranks first in the scale of manufacturing industry in the world. The number of manufacturing enterprises above designated size exceeds 320,000. There are a wide range of industries, rich product categories and sound industrial systems. The virtual reality technology is rich in applications and vast in space.
