Abstract
A finite element analysis model which include rotor,oil film,stator core,stator frame was established to research the dynamical characteristics of large turbo-generator stator.Through a comparative study on the stator modal test and finite element calculation results,the necessary optimization of finite element model was applied.The calculation results and the test results verified the validity and reliability of the finite element analysis model.Based on the optimization model,in order to get better dynamic characteristics of the structure ensure the unit operate safety and stable, optimization was applied to adjust the dynamical characteristics of stator.关键词
