Multistage Asymmetric Rotors Coaxial Measurement Stacking Method Based on Minimization of Exciting Force

The unbalanced exciting force of high-speed rotary asymmetric rotor equipment is the main factor causing vibration. In order to effectively suppress vibration equipment, paper establishes a multistage coaxial measurement stacking method that minimizes force. By analyzing propagation process centroid assembly and relationship between geometric center single rotor, model based on established. genetic algorithm used optimize unbalance rotors. Combined with principle under force, amplitude left bearing at different rotation speeds minimization random phase analyzed. Finally, experimental rotors are dynamically measured, combined rotors’ error experiment. results confirm minimum smaller than three-speed modes, optimization rate reached 73.2% 9000 rpm, which proves effectiveness in minimizing
