UNIVERSITY OF CINCINNATI, CINCINNATI, OHIO,
9/90-12/95
Research Assistant
Performed the finite element analysis modeling and modal test on two Highway bridges, 1 building, under ODOT project to conduct the nondestructive evaluation. Achieved excellent test/analysis correlation is obtained. The maximum frequency error of the updated model is 6% for 18 modes with MAC values close to 1.0 for all modes. Wrote a MATLAB program with functions of finite element modeling, model reduction, analysis/test correlation and optimization.
JILIN UNIVERSITY OF TECHNOLOGY, CHINA,

Research Engineer
Conducted research on vehicle development for First Motor in China. Wrote research proposals; Interacted with industry clients. Developed a money-saving method to aid design cycle using perturbation method. Designed an automobile frame CA141 using this method for the First Motor of China. Obtained desired dynamic characteristics. Designed the procedures to predict dynamic characteristics of a rocket after it was launched based on its ground test for Aeronautics and Aerospace Institute of China.\ In charge of a project - supported by Natural Science Foundation of China: the Random Vibration Analysis of Structures with Uncertain Properties. Quantified the effect of manufacture error on the dynamic characteristics of complex structures. Worked on a project: Perturbation Analysis of Structures with Repeated Eigenvalues supported by Chinese Natural Science Foundation.
