Methods and apparatus for assembling rotatable machines

摘要

A method (300) and apparatus for assembling a rotatable machine is provided. The machine includes a plurality of blades that extend radially outwardly from a rotor. The method (300) includes determining (302) a moment weight of each blade in a row of blades, determining (304) a geometric parameter of each blade in the same row of blades, and determining (306) a mapping order of each blade using the moment weight and the geometric parameter. The apparatus includes a computer system that includes a software product code segment for minimizing imbalance in a bladed rotor wherein the segment is configured to receive a moment weight value for each blade to be installed in said rotor, receive a geometric parameter value for each blade to be installed in said rotor, calculate a blade location on the rotor based on the received values, and generate a blade map based on the calculated location.
