Embodiment Construction

[0023] The specific embodiment of the present invention sees Figure 1-4 :

[0024] A rotor test bench with flexible support, such as figure 1 and figure 2 As shown, it includes a rotor system and a test bench base 2. It is characterized in that a flexible support device is arranged between the rotor system and the test bench, and the flexible support device can adjust the rigidity of the rotor system. According to the different fault forms of the rotor, the dynamic behavior of the rotor system under different support stiffness is studied to better guide the practice.

[0025] Preferably, the flexible supporting device includes two first flexible supporting devices and a second flexible supporting device with the same structure, and the first flexible supporting device and the second flexible supporting device are respectively arranged on the left and right sides of the test bench, so as to facilitate the realization of two flexible supporting devices of the rotor system. ...

Abstract

A rotor experiment table with a flexible support comprises a rotor system and an experiment table base. The rotor experiment table is characterized in that a flexible supporting device is arranged between the rotor system and the experiment table. The experiment table is suitable for the field of rotary machinery fault diagnosis technology. The rotor experiment table with the flexible support has a rigidity-adjustable function. The rotor experiment table is composed of the flexible supporting device, the rotor system, etc. Influences of vibration, rotating speed, torque and centering offset to a rotor device can be researched. The rotor experiment table has advantages of simple structure, low production cost, low use cost, high convenience in operation, high practicability, wide application prospect in dynamic experiment researching and teaching fields of rotary machinery, relatively high popularization value and relatively high application value.

Description

technical field [0001] The invention relates to the technical field of performance testing and fault diagnosis of rotating machinery, in particular to a rotor test bench with flexible support. Background technique [0002] Rotor is an integral part of rotary machinery, and the rotor system is also a part that is prone to failure in rotary machinery. The operation status of the whole machine is greatly affected by the operation status of the rotor system. The performance test and fault diagnosis of the rotor system are important guarantees to ensure the safe and reliable operation of rotating machinery. [0003] The usual research considers that the supporting structure of the rotor is rigid, without considering the influence of the supporting stiffness on the kinematic characteristics of the system. But in reality, the stiffness of the rotor support structure is different under different installation environments. Under certain flexible supports, the kinematic characterist...
