MESYS Calculation Software

In the overview also the natural frequencies can be shown. If a frequency is selected, the corresponding mode shape is shown in the graphics. Three displacements and the torsion angle are shown in 2D view. In 3D view the mode shapes are shown animated.




Available results are:

'f': frequency in Hz and per minute

'D': Damping ratio of the mode in case a damping is defined

'Type': Try's to classify the type of mode based on the kinetic energy of the modes. A numeric value for the whirl direction is given. +1 is a circular forward whirl, 0 is a linear orbit and -1 is a circular backward whirl.
