    摘要: A method and a system for determining radial clearances in a rotating machine are provided. The rotating machine includes at least one shell, at least one rotor, and at least one stationary component. The method includes creating a finite element model for at least one component within the rotating machine, creating a cycle deck data file for the rotating machine, determining an initial clearance versus time, and determining an initial clearance versus location. The system includes a client system including a browser, a centralized database for storing machine information, and a server system configured to be coupled to the client system and the database wherein the server system is further configured to receive machine information from the client system, store finite element model information in the centralized database, track machine information, update the centralized database periodically with newly received machine information to maintain machine information, and provide machine information in response to an inquiry.
