"Key technologies and applications of dynamic design and manufacturing of large-scale heavy duty mechanical equipment", led by Huazhong university of science and technology and co-researched by nanyang erji group, won the second prize of 2016 national science and technology progress award, and was commended in the great hall of the people on jan 9.It is the country's highest technology podium since the company's 3,000-meter vehicle rig won the award in 2003.
All along, the Nanyang RG group is very particular about production-teaching-research combination, successively with Tsinghua university, Huazhong university of science and technology, China university of petroleum and other institutions set up extensive cooperative relations, in the low temperature materials research and development and application, digital deep well drilling equipment, drill important progress in automation control and so on, not only has achieved fruitful research results, and improve the company's capacity for independent innovation and product market competition.
It is understood that the large heavy load mechanical equipment studied in this award-winning project is widely used in the pillar industries of national economy construction, such as energy, electricity, transportation, port and mining, and has the main characteristics of heavy load bearing, strong dynamic load and extreme environment operation. With the expansion of operating range and the improvement of performance demand, large heavy duty machinery, such as oil and gas drill and hydraulic support for fully mechanized coal mining, can carry a load of up to 1,000 tons, with a maximum dynamic load of more than 10,000 tons.At present, most of the similar equipment used at present adopts static design based on load coefficient, which can only exchange the huge structure and high manufacturing cost for operation safety, but it is often difficult to achieve expected results.
The winning projects in the study, to reveal the mechanism of mechanical dynamics behavior, puts forward several coupling structural dynamics modeling and parameter identification method, the innovation of the large overload electrical and mechanical equipment and dynamic characteristics of temporal and spatial evolution parameter sensitivity analysis method, invented the large heavy mechanical and electrical equipment structural dynamics modification and dynamic performance test technology.By adopting innovative dynamic design and manufacturing methods, it has effectively solved the key and major problems of ensuring safety and reliability of equipment and manufacturing economy, and filled the domestic blank.
