ACHIEVEMENTS OF MAJOR PROJECT "THE NONLINEAR DYNAMIC PROBLEMS OF LARGE SCALE ROTOR SYSTEMS"

The plans of the major project of National Science Founds, NONLINEAR DYNAMIC PROBLEMS OF LARGE SCALE ROTOR SYSTEMS (No. 19990510), was completed together by all partners who made great efforts during the four-year research process. The project passed the final check organized by two departments of NSFC, the department of mathematical and physical sciences and the department of engineering and material sciences. By now the project has won one secondary prize of National Natural Science and other four provincial prizes (including one first-class prize in natural science, one first-class prize and two secondary prizes in Science and Technology Progress) . Its academic achievements have pushed our country in the front of the world in some scientific fields, such as nonlinear dynamics, rotor dynamics, mechanical fault diagnosis etc. , and have played an important role in the Science and Technology Progress of electric power industry in China.
