From the growth experience and resume, Xuan Fuzhen, who was born in the hometown of Confucius and Mencius, is not much different from many outstanding new Shanghainese of the same age: he was admitted to Shandong Polytechnic University with excellent academic performance and was sent to graduate school after graduation. After graduation, he stayed in the Department of Chemical Engineering to teach, and two years later, he entered the Chemical Machinery Department of East China University of Science and Technology to pursue a doctorate. Speaking of majors, Xuanfu's rare science is chemical machinery, and his master's degree is engaged in solid mechanics. He has a special liking for returning to chemical machinery. It is such a cross-disciplinary experience that he has a certain understanding of engineering and industry, and also has a scientific foundation, which has laid a solid foundation for his future academic development. After graduating from Ph.D., Xuan Fuzhen chose the latter among the choices of enterprise development, government departments or staying in school. In the interview, Xuan Fuzhen told me that his lifelong pursuit of scientific research and teaching and educating people began in the days after his doctoral graduation, especially when he really felt like doing scientific research, which stemmed from his efforts after his doctoral graduation. "At that time, doing scientific research became the only important thing in life. I seldom rest on weekends and holidays, and I feel energetic. What impressed me the most was that I spent several Spring Festival in the laboratory in those years. Taking care of housework and taking care of children is a wife's silent promise. Every night after 12, she comes home, which is not only the joy of achieving phased results at work, but also the embarrassment of his wife and children. " Shanghai Natural Science Foundation is the first scientific research project independently undertaken by Dr. Xuan Fuzhen one year after graduation. Since then, it has successively obtained a series of talent plans and scientific research projects, such as the Shanghai Science and Technology Star Program, the Youth Fund of the National Natural Science Foundation, and the Fok Yingdong Young Teachers Fund of the Ministry of Education. More importantly, during this period, he started cooperative research with Shanghai Steam Turbine Works. Focusing on ultra-supercritical steam turbine, the bottleneck technology of major equipment localization, which is known as the "crown jewel of manufacturing industry", he carried out life analysis and design method research, which opened the cooperation between China University of Technology and Industry-University-Research of Shanghai Steam Turbine Factory, and also became the fuse for his academic research to enter electrical equipment from petrochemical industry. Talking about this experience, Xuan Fuzhen said with emotion that it was not only the beginning and transition period of his scientific research, but also improved his taste and appreciation of science and technology. The author believes that this may be another case of rewarding diligence by heaven. Ten years of grinding a sword, dare to pick the crown pearl.
"The life design of key components of steam turbine was first put forward by the enterprise from the project establishment procedure, but the initial cooperation intention originated from our chat". At present, the domestic advanced steam turbine technologies, such as million kilowatt ultra-supercritical steam turbines and nuclear power equipment, are all imported from foreign companies such as Mitsubishi, Toshiba and Siemens. The core technologies of these products, such as life design and assessment, do not belong to the transfer category. This not only limits the localization process of products, but also puzzles enterprise technicians for a long time: what is the basis for the life design of key components of new high-parameter steam turbines? How will the long-term use and the change of use conditions affect the service life? How to control it in design? By chance, Xuan Fuzhen and others learned that these problems concerned by enterprise technicians were the directions involved in the projects he undertook and participated in with his mentor and research group during his doctoral period, so they persuaded enterprises to cooperate on this difficult problem. At that time, Xuan Fuzhen couldn't imagine that the research direction decided by an accidental chat with the technicians of the steam turbine factory-the life analysis technology of key components of large steam turbines actually touched the * * * problem of modern manufacturing industry, and it was one of the key technologies for the localization of ultra-supercritical steam turbines known as the "crown jewel of manufacturing industry". In the interview, Xuan Fuzhen introduced this information to me, which gave me a long insight: the welded rotor of the world's largest nuclear power steam turbine being developed in China is the most difficult and valuable part of steam turbine equipment, and the nuclear calibration technology to ensure its smooth operation, service life and process reliability is at the core. For example, its design life is 30 years, so the core content of life analysis is to figure out how to control life and when it will reach the critical point. This involves not only various new technologies, but also many factors such as new materials. Over the years, the research direction of Professor Xuan Fuzhen and his team has gone from safety assessment and failure analysis of chemical equipment to life analysis and safety control of advanced energy equipment. Last year, Professor Xuan Fuzhen was supported by the Qixing (Tracking) Program, which involved the safety assessment and testing technology of nuclear pressure vessels. Speaking of this, Professor Xuan Fuzhen said confidently that the research of pressure vessel technology is our professional route. Compared with civil equipment, the safety requirements of nuclear pressure vessels are higher, especially the influence of radiation needs to be considered. Through further modification and supplement, the life cycle analysis technology we proposed at present can be completely transplanted to nuclear power equipment. The accident of Fukushima nuclear power plant in Japan, fortunately, the pressure vessel has withstood the test. If something goes wrong with this equipment, it's really out of control. "Advanced life design technology should be reflected in the fact that the life span of 60 years should be 60 years, which requires extremely high manufacturing technology of equipment and needs to be guaranteed from the whole life process of design, manufacturing, operation and maintenance". For the introduction of equipment life-cycle design technology, please refer to the summary of Life-cycle Prediction and Safety Assurance of Mechanical Structures written by Xuan Fuzhen in this issue. Learn to extract scientific problems from engineering. In recent years, East China University of Science and Technology has made great achievements in solving engineering technical problems and basic theoretical research, which is also evident from the fact that Huali occupied one seventh of the 49 first prizes of science and technology in Shanghai in 20 10. Professor Xuan Fuzhen's work performance in these years also reflects this feature of East China University of Science and Technology. His research is not only supported by the National Natural Science Foundation of China and the key projects of Shanghai Natural Science Foundation, but also undertaken the 863 Program, the National Science and Technology Support Program, the Seven-Star Program and a large number of enterprise scientific research projects. From associate professors to outstanding doctoral supervisors and professors, Xuan Fuzhen attributed all this to "good luck". If we want to sum up the secret of development in recent years, Xuan Fuzhen said that it would benefit from doing a good job of "extracting scientific problems from engineering projects". "For example, the safety assessment of pressure vessels is itself an engineering and technical problem. Our team made a failure assessment chart of pressure vessels, which is a tool to solve practical engineering problems. Furthermore, the scientific element is to understand the different failure modes and mechanisms of pressure vessels, and use interdisciplinary methods such as mechanics and materials science to obtain systematic knowledge of their failure processes and principles, and propose a fundamental solution to safety problems. " Xuan Fuzhen admits that it is not easy to really extract scientific problems from engineering. "Research topics need to pay attention to' standing on top of the world', but applied basic research is between' heaven' and' earth', and we are also working hard in this direction, which is one of the difficulties that plague everyone." The first task of a professor is to cultivate students in the process of communication with Professor Xuan Fuzhen. I think he has a lot of opinions on current hot topics such as scientific research evaluation and student training. For example, in his School of Mechanical and Power Engineering, although in the past 10 years, the research funding has increased by 10 times. But he clearly realized that the first priority of university teachers is to train students, and scientific research should also serve this goal. "Doing scientific research is only one of the responsibilities of college teachers. What is more important is to bring out a group of good students through high-level scientific research. University research needs to start with cultivating students and let them stand tall. Standing on the ground refers to theoretical achievements, rooted in reality, solving engineering problems and forming innovative thinking and ability. " Professor Xuan Fuzhen believes that publishing papers is an important way to reflect scientific research achievements, but it is not the only way. The evaluation of researchers in different fields and directions needs to be treated differently. Talking about the cultivation of students, Professor Xuan Fuzhen said, "I don't encourage graduate students to publish some innovative papers, but make clear the problems and form a system before writing papers." Cultivating innovative ability is only one aspect of postgraduate education, and moral character and cultural accomplishment are equally important. On the other hand, the ability of communication and expression is also an essential element for high-level talents. The recently published papers are as follows:
