Whirling of Shaft Apparatus
Description & Specification
Technical Specifications
The modes of oscillation and resonances of rotors with continuous mass distribution can be clearly demonstrated using this unit. Due to the use of thin, elastic rotor shafts made of high-strength steel, the oscillatory phenomena can be easily understood. A range of shaft diameters and the free choice of the bearing arrangement make it possible to perform a wide variety of experiments. Adapters in the bearings compensate for different diameters; catch bearings limit the amplitude of the oscillation. The freedom of movement of the rotor is assured by an elastic coupling. A Laval rotor with discrete mass distribution can be assembled using a mass disc. As a supplement to this unit, a set of vibration sensors is available. These enable the path of the rotor to be displayed on an oscilloscope.
