Dynamics R4 helps in...

Design...

This software is a mathematical test facility that allows parametric studies and optimization of rotating machinery dynamics. Wide variety of the structure simulating elements and the friendly interface facilitate buildup of accurate system models.

Development...

The code may be applied to simulation of vibration problems arising in experimental tests and during rotating machinery operation. The simulation results may explain details of the damaging process.

Model based diagnostics...

The unsteady and non-linear approaches allow simulation of various systems dynamic response. So there arises a possibility to create calculation based diagnostic algorithms without numerous expensive specific tests.

Research activities and education…

Researchers and scientists may create their own elements to simulate non-linear effects. The new elements may be integrated in the Dynamics R4.
The code may be used for teaching students the rotor dynamics and for solving educational examples, laboratory practice support, etc. Students also may use the S/W for self-instruction purposes.

  • Oil Whirl and Whip, 2009
    oil whirl and whip Oil whirl is a common problem with journal bearings used on machines equipped with pressure lubrication systems operating at relatively high speeds.
    If the shaft is moved off center due to load, eccentricity, or imbalance, then the clearance on one side of the bearing will be greater than that on the other side.
    As the lubricant rotates at less than 50% of shaft speed, it must squeeze through the narrow area where the shaft is closest to the bearing. The average speed of the lubricant increases inside the gap and slows down when it leaves the gap. Such a speeding up and slowing down process creates turbulence on both sides of the gap, and a vortex develops in the high-pressure lubricant zone.
