The research group led by TC-3 members has conducted
research and development of BTT systems. Three test rigs
have been set up and put into laboratory tests. They use a single
rotor and trial produces damaged blades with different
crack forms and locations. The air jet system is used to simulate
aerodynamic load conditions. Pre-flaw is demonstrated
in different parts of the blade, and the effect of cracks on blade
vibration was studied to capture the fault characteristics.
Experimental verification of BTT and blade tip clearance measurements
under different rotating speeds, clearance amounts,
and aerodynamic excitations was carried out (Fig. 1c). A hardware
system based on optical sensors has been constructed.
The software system has also been researched to collect the
BTT data. BTT missing data fixing, parameters identification,
and blade dynamic strain reconstruction algorithms are embedded
in this system. The fault diagnosis methods are now
under research and will be added to the systems soon.
TC-3 Activities
Guided by the main goals of TC-3, the members and chairs are
dedicated to plenty of activities that focus on research related
to condition monitoring and fault diagnosis, including the
organization and participation of academic conferences, teaching
and lecturing activities, and public service.
Academic Conferences
In terms of academic conferences, the activities of TC-3 members
and chairs include the technical support of conferences,
the organization of special sessions, and the presentations of
conference papers at events such as the International Conference
on Sensing, Measurement and Data Analytics in the Era
of Artificial Intelligence (ICSMD 2020 and 2021) and the IEEE
International Instrumentation and Measurement Technology
Conference (I2MTC 2020, 2021, and 2022).
ICSMD: The ICSMD, which is supported by the IMS TC-3 and
TC-7, allows experts and scholars to meet and exchange ideas
on the development of the latest sensing methodologies, measurement
technologies, and data analytics approaches with
applications in various engineering domains in the era of artificial
intelligence. It has been successfully held for two years,
attracting over 300 participants with 240 papers (Fig. 2).
TC-3 chair Prof. Weihua Li was one of the Technical Program
Co-chairs of ICSMD 2020 and 2021, and Prof. Xuefeng
Chen was one of the Honorary Chairs of ICSMD 2020. The
members of TC-3 participated in the Special Sessions (SS)
such as " NDT&E and Intelligent Inspection System, " " Weak
Signal Processing and Incipient Fault Detection, " " Intelligent
Process Monitoring and Optimization for Advanced
Manufacturing Systems, " and " Machine Learning for Measurement
Uncertainty and Decision Making in Machine
Intelligent Diagnosis. "
In addition, papers on aero-engine bevel gear fault diagnosis,
dynamic modeling of the gearbox, and intelligent fault
diagnosis of rolling bearings were orally presented during the
conferences [3]-[6]. Furthermore, student activity to advertise
IEEE IMS was held by the Student Branch Chapters (SBC) during
ICSMD 2020, attracting more than 50 domestic students to
become members of IEEE IMS and SBC (Fig. 3).
I2MTC: TC-3 Chair Prof. Weihua Li was dedicated to the organization
of the special sessions on " Machine Leaning for
Measurement Uncertainty and Decision Making in Machine
Intelligent Diagnosis " of I2MTC 2022, " Advanced Measurement
and Data Analytics for Industrial Equipment Health "
of I2MTC 2021, and " Advanced Measurement and Data Analytics
for Industrial Equipment Health Monitoring " of I2MTC
2020. The members of TC-3 participated in the conferences
and orally presented papers on related fields such as machine
anomaly detection, aero-engine fan acoustic mode detection,
and bearing fault diagnosis [7], [8].
Teaching and Lecturing
TC-3 chairs and members are active in organizing and teaching
courses, such as Measurement and Test Technology, Fault
Diagnosis of Mechanical System, Robotic Systems Design, Advanced
Measurement Techniques, and Academic Writing. In
addition, seminars are held regularly to discuss advances in
condition monitoring and fault diagnosis. Moreover, scholars
and experts in this field are invited to give speeches and lectures,
which provides great platforms for TC-3 members and
followers to keep in touch with the latest research achievements
and promotes communication between TC-3 and
international research teams.
