The invention belongs to the technical field of high-speed dynamic balance, and particularly discloses a high-speed dynamic balance correction method for a flexible rotor, which comprises the following steps of: 1, installing the flexible rotor to be measured in a high-speed dynamic balance machine, and creating a configuration file of the flexible rotor in measurement software; 2, measuring an original vibration vector of the flexible rotor by using measurement software; 3, performing trial weight measurement on the flexible rotor, and measuring a weighted vibration vector of the flexible rotor by using measurement software; 4, calculating the correction value of the flexible rotor according to the measurement results in the step 2 and the step 3; 5, correcting the flexible rotor according to the correction value of the flexible rotor; and 6, carrying out dynamic balance detection on the corrected flexible rotor. According to the method, the problem that the dynamic balance precisionof the rotor is not high due to inaccurate calculation of the unbalance amount of the flexible rotor in the prior art can be solved.
Description
technical field [0001] The invention belongs to the technical field of high-speed dynamic balance, and in particular relates to a high-speed dynamic balance correction method for a flexible rotor. Background technique [0002] A flexible rotor refers to a rotor whose operating speed is close to or exceeds the first-order bending critical speed of the rotor. As the capacity of the unit increases, the axial dimension of the rotor of the unit is also increasing. The thin and long rotor has increased flexibility, which makes the critical speed of the rotor drop greatly, and the working speed will exceed the first critical speed or the second critical speed. , The third order critical speed. The flexible rotor will produce dynamic unbalance at high speed, and then generate vibration and noise, which will affect the service life and transmission efficiency of the rotor, and the rotor is an important part of the mechanical system, and its unbalance will affect the entire unit syst...
