Description
Technical field
The utility model relates to the experiment table of overall machine vibration monitoring and control field, be specifically related to a kind of balance test platform, the unbalance forced vibration of flexible rotor axle system can be simulated, effectively reproduce the energy imbalance that rotating machinery produces, for the research of rotor theory of dynamic and method.
Background technology
Unbalance is the modal fault of rotating machinery, and its processing procedure is also complicated in all faults.For the balance method of flex rotor spot dynamic balance, modal balance method and the large class of influence coefficient method two can be summarized as, from counterbalance effect, although said method can realize the desirable balance of rotor, but due to the diversity of flex rotor structure and the complicacy of the unbalance situation of reality, simultaneously, due to the strict restriction of the factor such as dynamic performance of the position of cycling start number of times, rotor balancing face and vibration measuring point and number, position, axle system spot dynamic balance up to the present still still a kind of examination under theoretical direction survey process.
At present, Bently company of the U.S. produces the dynamic balance experimental bench of single shaft, but the balance test not connecting into axle system is arranged.The rotor oscillation simulated experiment platform bearing seat that domestic Dong great vibration measurement instrument factory produces and base are fixed by slide block guide rail, and sensor stand and base are fixed by monolateral screw, and positioning precision is lower, easily introduce non-power frequency fault, obscure the research to balancing fault.

Although this balance test platform can simulate the unbalance forced vibration of flexible rotor axle system easily, effectively reproduce the energy imbalance that large rotating machinery produces, for the research of rotor theory of dynamic method.
But axle system rotor is connected by rigidity, half elasticity or spring coupling, and shaft coupling is because material structure is uneven, foozle, alignment error, make not overlapped with rotation by the principal axis of inertia of shaft coupling barycenter, shaft coupling has small bias will produce larger centrifugal intertia force, larger annex dynamic pressure will be produced to bearing, thus affect the experiment of dynamic balancing of axle system.
Simultaneously by increasing the weight of dish adds screw and simulates unbalance amount, because screw hole location is fixed, making the unbalance amount data area simulated narrower, effectively can not simulate axle and tying up to unbalance situation in real work.
