Method for machining an integrally bladed rotor |
摘要 |
A method for machining an integrally bladed rotor of a fluid-flow machine is disclosed. In accordance with an embodiment of the invention, the method includes the steps of: a) providing an integrally bladed rotor having a main rotor body and several rotor blades integrally attached to the main rotor body; b) determining the natural frequency of each rotor blade of the integrally bladed rotor; and c) machining at least one rotor blade of the integrally bladed rotor by removing material to adjust the natural frequency of the particular rotor blade to a specified value. |

1. A method for machining an integrally bladed rotor of a fluid-flow machine, comprising the steps of:
a) providing an integrally bladed rotor having a main rotor body and several rotor blades integrally attached to the main rotor body; b) determining a natural frequency of each rotor blade of the integrally bladed rotor; and c) machining at least one rotor blade of the integrally bladed rotor by removing material to adjust the natural frequency of the at least one rotor blade to a specified value; wherein the at least one rotor blade of the integrally bladed rotor is machined through material removal in an area of a radially inward lying transition section between the main rotor body and the rotor blade such that a radius of a fillet formed between the main rotor body and the rotor blade of the integrally bladed rotor varies as a result of the material removal. |
