Embodiment Construction
[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0036] Such as figure 1 As shown, the rotor model used in the dynamic balance experimental system of the embodiment is a single-span four-balance surface double-measuring-point rotor model. The total length of the rotor is 560mm, and each 8mm shaft segment is divided into a unit, which is divided into 70 units from left to right; B1 and B2 are rolling bearings located at nodes 8 and 65, P1, P2, P3 and P4 are weighted balance surfaces located at nodes 18, 30, 42 and 56, S1 and S2 are vibration sensors, and the measurement system Unbalanced response, located at node 24, node 48.
[0037] Such as figure 2 As shown, the rotor system experiment platform of the embodiment is composed of motor speed controller, multi-balance rotor system, sensors, signal pre-processor, signal acquisition instrument, host computer, etc.; in the experiment, the multi-balanc...
