Abstract

As the basis of dynamic analysis, modal analysis can be used to determine the vibration characteristics of mechanical institutions themselves, briefly expounds the basic principle of modal analysis and modal analysis under the environment of ANSYS, and the steps, and a specific example, for turbine rotor calculation of modal analysis shows that the method of modal analysis in ANSYS software, the results show that this method for determine the vibration characteristics of the mechanical structure works, can fully meet the requirements of structural design.
