Machinery Fault Simulator (MFS)

The Best Tool Available for Learning Machinery Diagnosis

Description:

To gain an in-depth understanding of different vibration signatures, controlled experiments on a device that emulates real world machinery are needed. While analysis of a single machinery fault may be beneficial, there are many occasions when the analysis of the interaction between dynamic stiffness, resonance, and speed is essential in order to gain an understanding of real world vibration spectra. With the MFS, the expertise required to diagnose industrial machinery problems in well controlled experiments can be developed and enhanced. With a plant running at full production, it is virtually impractical to gain an understanding of the kinetics and dynamics of machinery without adversely affecting production and profits: The MFS enables offline training and experimentation which in turn will minimize production downtime.

    Smart Design Makes the Simulator Robust and Easy to Use

    The MFS is designed to be both versatile and easy to operate. The simulator is constructed with a split bracket bearing housing, a sliding shaft, rotors with split collar ends, couplings, pulleys, a multiple belt tensioning and gearbox mounting mechanism, and reciprocating system; all of which are designed to be easily removed and replaced between various experiments.

    The Machinery Fault Simulator (MFS) is our most popular model, having a larger baseplate and a more powerful motor. Compared to the MFS-Lite, it adds capabilities to study machinery defects found in gearboxes, belt drives, reciprocating mechanisms, induction motors, pumps, and compressors.
