flexural vibration of the elastic shaft

Description:

• This accessory setup enables the response of an elastic rotor to unbalanced excitation to be studied.
• The subcritical, supercritical and resonance running states can be demonstrated.
• A comparison of the orbits (path curves) in the subcritical and supercritical range is of particular interest.
• The field balancing of elastic rotors is another area which can be investigated.
• The supplied pendulum ball bearings ensure full mobility of the shaft.
• The safety bearing limits the amplitudes to harmless values at speeds close to resonance.
• The accessory setup is mounted on the base plate of the machinery diagnostic base system PT 500.
• To measure and evaluate the experiment, the computerised vibration analyser PT 500.04and two displacement sensors PT 500.41 are required.
• It includes all the necessary sensors, a measuring amplifier and analysis software to record the vibration phenomena.
