The final of the 2025 New Domain and New Quality Innovation Competition, hosted by the Ministry of Industry and Information Technology, successfully concluded in Qingdao.
Under the guidance of the Graduate School of Southeast University and the School of Mechanical Engineering, the team consisting of He Junzeng, Li Hongyu, Liu Jiaxuan, Hao Youming, Wang Wenxiang and Yu Guanting (Instructors: Fei Qingguo, Zhang Dahai) participated with their project Research and Verification of Vibration Problems in the Whole Turboshaft Aero-Engine.
As the only project from Southeast University to advance to the national finals, the team went through fierce competitions in the national preliminary round, initial selection round and final round, and finally won the Excellence Award.
This achievement fully demonstrates the courage to challenge and the spirit of relentless innovation among teachers and students of the School of Mechanical Engineering.
This competition is co-hosted by the Ministry of Industry and Information Technology and the People’s Government of Qingdao. Under the theme of Intelligence Gathering in New Domains, Wisdom Integrating into New Quality, it focuses on five major fields: high-end instruments and manufacturing equipment, artificial intelligence, cyberspace security, unmanned systems, and aerospace. The competition consists of two tracks: "Free Exploration" and "Demand-Oriented Propositions", with two participant groups: "University Teacher-Student Group" and "Innovative Enterprise Group".
A total of 770 teams advanced to the preliminary round, and more than 200 teams from universities including Northwestern Polytechnical University and Beihang University, as well as enterprises such as Qingdao High-End Bearing Research Institute, entered the final round after intense competition.
The teacher-student team from the School of Mechanical Engineering targeted key bottlenecks in the service and development of China’s current and next-generation advanced turboshaft engines: the lack of effective methods for whole-engine vibration analysis, insufficient basis for vibration suppression, and shortage of equipment for experimental verification. The team proposed an integrated approach for whole-engine vibration analysis and structural optimization design, and developed special test equipment for aero-engine whole-engine vibration tests, which significantly improved the level of whole-engine dynamic analysis. The research results have been successfully applied to the development and modification of a certain type of turboshaft engine in China. The innovative and striving spirit demonstrated by the team has won unanimous recognition from the judges and competitors.
