APPLICATIONS
Using the Simulator offers you a wide range of benefits in developing your understanding of predictive maintenance and learning to recognize the signatures of various machine faults. Different types of studies can be done with application specific kits. Each kit is designed to fit on the basic simulator. Application notes and exercises provide a cost effective self-paced training program. The following list indicates some of the many ways the simulator can increase your knowledge of machinery diagnosis and vibration analysis.

Shaft Alignment Effects
Misalignment between two mating shafts is the most common cause of machinery deterioration. A properly aligned machine can save a factory 20% to 30% in downtime, replacement parts, inventory, and energy consumption. The simulator provides:
Calibrated dials to introduce known amounts of parallel and angular misalignment
Easy ways to study misalignment effects and methods of correction
Learn effects of speed, coupling and rotor stiffness on misalignment signatures
|
Balancing
Unbalanced rotors are a very common cause of machinery malfunction. An improperly balanced machine has many hidden costs in downtime and parts due to accelerated wear and performance issues. The simulator provides for controlled study of unbalance:
Center and over hung
Single and multi-plane
Eccentric and cocked rotor effects
Critical speed effects

Rolling Element Bearing Fault Signature Analysis
Most common machines are fitted with rolling element bearings. Many malfunctions damage bearings first. It is essential to learn bearing defect signatures in presence of other complicating effects so that malfunctions are detected prior to catastrophic failure.
Deliberately faulted bearings fit the standard rotor shaft
Waveform and spectral recognition of classic bearing defects

Resonance and Critical Speed Studies
A proper understanding of resonance phenomenon is fundamental for minimizing downtime and maintaining the sound health of production machinery. The simulator along with the resonance kit is an ideal tool for an in-depth study of resonance and lateral critical speed phenomena.
Critical speeds below 2000 RPM simulate real world operating conditions and improve safety
Study effects of mass and stiffness on resonance frequencies and mode shapes
Study damaging effects of resonance and develop control methods
Study beating due to closely spaced vibration modes
Study rotor stability and non-linear dynamics for chaos modeling
|
Sleeve Bearing Effects
Many high speed machines are designed with sleeve bearings. Sleeve bearings are inherently quieter than the rolling element bearings, but they exhibit different rotor dynamics and problems. The modular design of the simulator makes it easy to install grease lubricated sleeve bearings.
Waveform and spectral recognition of worn or loose fitting bearings
Fits the standard rotor shaft with grease lubricated, babbitt lined, sleeve bearings
Bearings split so that plastic shims may be used to open the clearance to simulate real world conditions
Shaft orbital analysis
Examine heat generation as a function of alignment and bearing clearance
