| Abstract: | Based on the dynamic similarity, three key technologies for rotor dynamic modeling are presented, and taking a gas turbine modeling as an example, the key technology is verified The dynamic characteristics of the gas turbine are studied by there methods, and the results are compared with the experiment. The results show that the accuracy of dynamic analysis is mainly determined by the modal. The there key modeling techniques can reflect the characteristics of the structure and can be used in the dual-rotor system with similar structure. |
