Abstract EN
As rotary mechanical structure becomes more complicated, difficulty arises in receiving prime correction mass and optimum balancing plane efficiently.
An innovative modal balancing process for estimating the residual unbalance from different equilibrium plane of complex flexible rotor system is presented.
The method is based on a numerical approach with modal ratio among measurement points (MRMP) coefficient and triple phase method (TPM).
The veracity of calculation result is verified by an academic rotor model.
The latter study in this paper is subsequently put forward through a power turbine rotor modeled by finite element method.
Simulation results show that proper equilibrium plane performs commendably in recognizing residual unbalance and reducing the vibration effect through the critical region.
Moreover, the inherent unbalance recognized by experimental data from a turbine rotor with slender shaft is found to be in certain difference under different counterweight combination.
Choosing suitable balancing planes will improve the accuracy of unbalance identification.
