Thinking and practice on school-running orientation of the Newly-established universities-A case study of North China Institute of Science and Technology
The Newly-established universities should be advancing with everlasting innovation by accurate orientation on the basis of their own actual situation.As the only university affiliated to the State Administration of Work Safety,North China Institute of Science and Technology is continuously exploring the development planning,teaching reform,the cultivation of talents and so on,orientating itself towards a modern multidisciplinary university and the first-class training base with the safety science and technology characteristics.
In order to study the unit's movement law,a transient dynamic response model of large hydroelectric machines is established.The model couples the whole unit such as main shaft,generator rotor,turbine runner and various bearing supporting,and involves consistent quality of the unit shaft,gyroscopic inertia and angular inertia.The finite element method and direct numerical integration method are used in the calculation.Through an engineering example,the numerical simulations of time-course response and axes contrail are respectively carried out when the units are acted under transient initial displacements and transient imbalance loads.The calculated results are discussed and analyzed.By means of comparison between calculated and measured data,their results are close.
