1. Product Overview
The rotor vibration test stand is a test device used to simulate the vibration of rotating machinery. It is mainly used in laboratories to verify the forced and self-excited vibration characteristics of flexible rotors. It can effectively reproduce the various vibration phenomena generated by large rotating machinery. Through different choices to change the rotor speed, stiffness, mass imbalance, shaft friction or impact conditions and the type of coupling to simulate the running state of the machine, and observe and record its vibration characteristics by the configured testing instrument. Therefore, this test bench provides an effective and convenient experimental method for specialized in vibration testing, vibration research and related laboratories in colleges and universities.
The test stand has a simple structure, a wide speed range, intuitive display, and is stable and reliable. It can realize the stepless speed regulation of the motor from 0 to 10000rpm.
Using the eddy current sensor, magnetoelectric speed sensor, photoelectric sensor or CUT-206 vibration balance analyzer or CUT-408 type vibration acquisition and analysis system produced by our company and the test bench, it can easily depict the Bode plot (width Frequency and phase frequency characteristic curve), vibration mode circle, axis trajectory diagram, frequency spectrum diagram, trend diagram, shaft center position diagram and rate of rise diagram, is a series of rotor test systems very suitable for scientific research, teaching and training demonstration.
Note: In addition to being compatible with CUT-206 vibration balance analyzer and CUT-408 type vibration collection and analysis system, this test stand can also be matched with other data collectors to form a rotor vibration test system.
