Dynamics R4 helps in...


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.


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 educationů

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.

  • Dynamics of the rotor system, supported by the active magnetic bearings, 2010
    AMB The solution presents the problems related to the use of the active magnetic bearings in rapidly rotated rotors of turbosets. The results of the dynamic analysis of the rotor supported by the active magnetic bearings are given. The possibility to control the rotor system changing the magnetic bearings stiffness and damping is considered. The behaviour of the rotor system during the rotor dropdown on the backup bearings and the following runout are investigated.
