October 23, Gabor Stepan, professor of the Department of Applied Mechanics at the Budapest University of Technology and Economics in Hungary, was invited to visit. Yan Fuping, deputy secretary of the school party committee, met with Professor Gabor Stepan in the third conference room of the Academic Conference Center.

On behalf of the school, Yan Fuping extended a warm welcome to Professor Stepan’s visit and briefly introduced the school’s achievements in talent training, discipline construction, scientific research and other aspects in recent years; he also expressed his appreciation for Professor Stepan’s previous contributions to our school’s scientific research, talent training, and international cooperation and exchanges. I would like to express my gratitude for the help in my work; I hope that Professor Stepan will further expand the cooperation space based on the existing cooperation with our school in the future and continue to achieve new cooperation and innovation results.

Professor Stepan expressed his great gratitude to the school for the invitation and warm reception, and praised Hefei University of Technology for its achievements in recent years. He introduced the educational situation of the Budapest University of Technology and Economics in Hungary and its achievements in the field of basic sciences, and discussed the possibility of further strengthening cooperation with our school in the field of engineering technology, especially in the field of new energy vehicles.

Zhang Sihong, Director of the International Affairs Office, introduced the school’s foreign cooperation and exchanges in recent years. Professor Lu Jianwei, deputy dean of the School of Automotive and Transportation Engineering, reported on the previous cooperation with Professor Stepan’s team.

The meeting was chaired by Bai Xiushan, Secretary of the Party Committee of the School of Automotive and Transportation Engineering.

After the meeting, Professor Stepan gave an academic report titled "One hundred years of wheel shimmy: Why is it still dangerous?" for teachers and students of our school in the first lecture hall of the new building of the School of Management. The report introduces that tire wobble is an unpredictable vibration that, although its incidence is low, may lead to catastrophic accidents. At the same time, dynamic analysis reveals the complex behavior patterns of single contact points and Coulomb friction in the tire wobble model. as well as time lag effects and nonlinear effects of partial slip caused by tire contact with the ground. Professor Lu Jianwei presided over the report meeting.

Professor Gabor Stepan is an academician of the Hungarian Academy of Sciences, an academician of the European Academy of Sciences, an academician of the International Academy of Production Engineering (CIRP), a foreign academician of the Estonian Academy of Sciences, the former chairman of the Department of Science and Technology of the Hungarian Academy of Sciences, and a former executive director and executive committee member of the International Union of Theory and Applications (IUTAM) . He has won many honors such as the "Thomas K. Caughey Dynamics" Award from the American Society of Mechanical Engineers and the "Szechenyi Prize", Hungary's highest science and technology award. Main research areas include the theory and engineering applications of nonlinear vibration and time-delay systems, such as stability and bifurcation theory, theoretical cutting, wheel nonlinear dynamics, traffic dynamics, robot vibration and stability, human body and robot balance problems.
