Abstract
A parametric modeling method for turbine components includes: Step S01: Importing turbine model parameters or creating new model parameters; Step S02: Obtaining the underlying formatted data of the turbine casing, seat ring, movable guide vanes, runner, and draft tube to be modeled; Step S03: Importing the formatted data of the corresponding components obtained in S0 and S02 into the corresponding modeling tabs; Step S04: Inputting the corresponding parameters according to the different component modeling tab interfaces, and then executing the corresponding component model generation command. The program uses encapsulated embedded logic to process the imported formatted data and, combined with the component feature parameters input in Step S03, generates the modeled component entity. The embedded logic includes one or a combination of the following technical solutions: creating arc surfaces by traversing arrays, generating spline curves from arrays, multi-section lofting, traversing array evaluation, scaling ratio linear interpolation, approximate conformal transformation mapping, circular array, sweeping, stretching, rotation, and vector movement.
