DAC Worldwide's Resonance Demonstration Kit (203-012) is a specialized product option available for use with all related vibration analysis demonstration products that allows for expanded realistic demonstration of system resonance due to imbalance, as well as the effect of a flexible shaft-on-shaft orbits and overall displacement on rotating equipment. The components easily mount on all Vibration Analysis Demonstration (203) devices in combination with standard pillow blocks, couplings, and motors.

Consisting of two, precision-machine and welded steel rotors, with provision for mounting temporary weights at 20 positions radially on each rotor, they also include expanding mounting hubs, and shaft set screws. An aluminum replacement shaft is provided as well.

This unique package of component allows for exaggerated demonstrations of resonance at critical speeds, exaggerated displacement due to imbalance, and the effect of elastic shafts in combination with resonance, misalignment and/or imbalance.
