报告简介


Aero-engine blades, often suffering from harsh environments such as high rotating speed, high temperature, and heavy load, are prone to crack damage or even fatigue fracture.Effective Blade health monitoring (BHM) is vital to ensure the operation safety of aero engines. The emergence of digital twin technology provides a viable tool for virtual-real interaction of a complex dynamic system, which can help to identify and quantify potential faults in the dynamic system, such as aero-engine blade damages. This presentation will focus on the critical technology for the implementation of digital twin-driven BHM, including high-fidelity vibration modeling, real-time vibration reconstruction, and sparse regularization-based blade damage identification. A brief overview will be presented first, followed by some advancements and challenges in this field.


报告主题2:Key Technologies of Shape-performance Integrated Digital Twin for Major Equipment

专家简介:

Xueguan Song is currently a Professor in the School of Mechanical Engineering, Dalian University of Technology. He has published more than 200 peer-reviewed papers (over 100 SCI papers), two books and two book chapters in various research fields including engineering optimization, computational fluid dynamics simulation and digital twins. His research interest includes multidisciplinary design optimization, surrogate modeling, AI and digital twin. He led the development of cloud-based and data-driven design optimization software DADOS (www.dados.com.cn). Dr. Song received many awards such as the Best Paper Award at QR2MSE2016 Conference, Best Poster Awards at CSO 2011 and PCO’2010 Conferences, and Honorable Mention Award in the PhD student paper symposium and competition at the 2010 ASME PVP Conference.


报告简介:

Digital twin is one of the key technologies to realize accurate prediction and reliable analysis of morphology and performance of major equipment. Considering the timeliness and accuracy requirements of the twin model, a shape-performance integration digital twin(SPI-DT) framework for major equipment is built. Additionally, six specific problems faced by building the digital twin of major equipment are discussed in detail, including “unrealizable calculation”, “inaccurate calculation”, “delayed calculation”, “unmeasurable data”, “incomplete measurement” and “inaccurate measurement”, and the relevant solutions and key technologies are given. The feasibility and validity of the proposed framework and key technologies are described by combining typical case, which provides a theoretical and methodical reference for the further application of digital twin in major equipment.
