Embodiment 1
[0047] This embodiment mainly verifies the validity and accuracy of the present invention.
[0048] 1. Composition of dynamic balance experiment system
[0049] Such as figure 1 As shown, the unbalanced fault is simulated by the rotor experimental system to study the effectiveness of the dynamic balancing method of the present invention. The hardware part of the system mainly includes several major modules such as Bently RK4 rotor test bench, eddy current displacement sensor 2, signal conditioning module, NI data acquisition module, and industrial computer. Among them, the rotor test bench is composed of three parts: the rotor connected to the motor 4, the bearing 5, and the mass disc 3. The eddy current displacement sensor 2 can test the radial vibration information of the rotor in real time, and the data acquisition module converts the analog signal representing the displacement information Convert it into a digital signal, and send it to an industrial computer for unbalan...
