ANV Teknik LTD. performs torsional vibration calculation. A torsional vibration analysis covering the torsional vibration stresses to be expected in the main shafting system including its branches is to be submitted to Class Society for approval.
Output Data / Results;
natural frequencies with their relevant vibration forms (modes)
forced vibratory loads (torques or stresses)
Calculated torsional vibration torques/shear stresses in all important elements of the system with particular reference to clearly defined resonance speeds for the whole operating speed range.
The results shall include the synthesised values (vectorial sum over all harmonics) for the torques / stresses
