Description

The complex provides research into the phenomenon of shaft resonance. The shaft drive is carried out by an asynchronous electric motor with frequency control of the rotation speed. Shaft movements are recorded by non-contact inductive sensors.
Composition: frame structure with protective casing; the shaft being examined; electric motor; a frequency converter; sensors for rotation speed and displacement of one shaft section; main and two additional disks for installation on the shaft; electrical control unit; ADC board; laptop.
Overall dimensions, no more, mm: 1100x400x300;
weight, no more, kg — 100.
Laboratory works:
1. Determination of critical shaft rotation speeds under various inertial loads.
2. Determination of critical shaft rotation speeds at different distances between supports.
3. Determination of the frequency response of the shaft under different inertial loads.
4. Determination of the frequency response of the shaft at different distances between the supports.
