Area of research: Structural health monitoring and damage identification, nonlinear dynamics and diagnosis of complex rotor systems.
Name of my University / Research Institute: Guilin University of Electronic Technology (GUET), China
Research period at the TU Darmstadt:
December 2013 to February 2015
Questionnaire to the Research Fellow
My field of research is fascinating. To laymen I would explain it in the following comprehensible manner:
With the development of science and technology and modern industry, rotating machinery is taking more and more important part in many fields such as power system, transportation, national defense and industry etc, thus the study of the dynamics of rotating machinery is fascinating and very important. A complicated machine system may vibrate violently due to nonlinearity that inherently exists in the system with faults, which can lead to the catastrophic failure in the worst case. Moreover, almost dynamic problems of large rotating machinery takes on the character of nonlinearity and non-stationary, thus it is significant in studying the nonlinear dynamics behavior of complex rotor system with fault.
My most important success in research to date is…
the development of nonlinear and non-stationary processing methods in the fields of structural health monitoring.
I’ve chosen the TU Darmstadt because of…
its a very good university and very strong in the engineering research. Research group of structural dynamics led by Prof. Dr. Markert and Prof. Dr. Schweizer make great progress in the fields of rotor dynamics, structure calculation and system identification.
If I were a student today, I would…
work hard on the theories in higher mathematics and mechanics because they are very important for the future research.
The perfect balance to a stressful working day is…
to travel with my family and to a rare paradise, away from the hustle and bustle of the city.
With the help of my host in Darmstadt I would like to…
do numerical simulation of the nonlinear dynamic behavior induced by faults in complex rotor systems as well as experimental verification.

You appreciate in your guest / your guest favourably impressed you by…
his kindness and professionalism in the fields of rotor dynamics.
You, your team and the TU Darmstadt benefit from your guest’s…
vibration-based methods for diagnosis of complex rotor systems and to compare the effectiveness and robustness with our model-based method through numerical simulations and experimental study.
