Biography: Cheng Yan is a tenured associate professor and a doctoral supervisor at the School of Aerospace Engineering, Xiamen University. He obtained both his bachelor's and doctoral degrees from Beihang University, studying under Academician Yin Zeyong. He has long been engaged in research on the design and optimization of key components of aero-engines. He has received honors such as the Young Elite Scientist Sponsorship Program by the China Association for Science and Technology and the High-Level Talent (Class B) of Fujian Province. He has published 20 SCI papers and 6 EI papers as the first author/corresponding author, holds 31 patents (authorized or pending) and 3 authorized software copyrights as the primary inventor, participated in the publication of 4 monographs, and delivered 6 invited reports. In the past 5 years, he has led multiple projects including basic research projects of the National Science and Technology Major Project, general/youth programs of the National Natural Science Foundation of China, and special funding/general projects of the China Postdoctoral Science Foundation. He serves as a dual-appointed expert and young visiting scholar at Taihang National Laboratory, a youth committee member of the Mechanical Design Branch of the Chinese Mechanical Engineering Society, and a guest editor of the journal Aerospace. He also acts as a reviewer for journals such as Chinese Journal of Aeronautics, Structural and Multidisciplinary Optimization, Propulsion and Power Research, and Energy.
Biography: Doctor Junhao Geng is a Professor and Doctoral Supervisor at the School of Mechanical Engineering, Northwestern Polytechnical University (NPU). He previously served as a Visiting Scholar at the University of Alberta, Canada. Currently, he holds the position of Director of the Industrial Augmented Intelligence Research Institute at NPU and serves as Deputy Director of the Shaanxi Provincial Engineering Research Center for Smart Factory Industrial Software. He maintains active memberships as a Senior Member of CMES, Professional Member of CCF, and Member of IEEE. Additionally, he contributes as a peer reviewer for several top-tier journals including IEEE TII, IJPR, IEEE TOC, and IEEE TVCG. His research focuses on digital and intelligent aerospace manufacturing processes for complex products (including aircraft, aero-engines, spacecraft, rail transit, and ships), industrial AR/AI and augmented intelligence, EWIS intelligent assembly and airworthiness certification, manufacturing LLMs and their applications, AR-based intelligent devices, and high-end industrial software systems. He has led over 10 national-level projects, alongside more than 20 industry-sponsored projects. His scholarly output includes over 100 publications in top journals (e.g., JMS, IEEE TII, CII, IJPR) and other authoritative publications, and recognition including three provincial Science and Technology Progress Awards and one National Teaching Achievement Award. A key accomplishment under his leadership is the development of CAPPFramework 5.0, a nationally renowned industrial software platform. Furthermore, he spearheaded the creation of first open industrial augmented intelligence platform-OpenIAI (www.openIAI.com). These systems have been widely adopted by nearly 100 manufacturers across aviation, aerospace, and other industries, significantly enhancing digital process design and management capabilities within large and medium-sized manufacturing enterprises.
Biography: A.Prof. Gao Zhiyuan received his B.S. degree in measurement and control technology and instrumentation from Harbin Institute of Technology, and Ph.D. degree in control science and engineering from Shanghai University in 2008 and 2014, respectively. He is currently an Associate Professor and PhD Supervisor at School of Mechatronic Engineering & Automation, Shanghai University. His research interests include aerospace vibration test analysis and control, adaptive control, active vibration control, and control system identification. He hosted and participated in more than ten research projects supported by National Key Research and Development Program of China, and National Natural Science Foundation of China, etc. In recent years, he has published more than 100 papers in Aerospace Science and Technology, Sensors and Actuators a-Physical, Smart Structures and Systems, etc.
Speech Title: Active Vibration Control of Aero-engine Blade Using MFC Sensors and Actuators
Abstract: As complex, thin-walled, and curved structural components, aircraft engine blades exhibit intricate geometries and operate under extreme environmental conditions. Blade vibrations pose significant risks to engine operational stability, necessitating advanced mitigation strategies. This presentation focuses on next-generation aeroengine blades incorporating piezoelectric materials for active vibration suppression, presenting both established and novel findings in three critical areas: optimal piezoelectric layout design, system identification, and vibration control methodologies. The objective is to advance the strategic placement of piezoelectric elements and enhance adaptive vibration control performance for smart, piezoelectric-enabled blades, thereby improving aeroengine reliability and efficiency.
