To perform the axial vibration analysis, the rot-bearing data file (.rot) must be built and opened. From the Main Menu, select Analysis and Axial Vibration as shown below.
The run time data screen for the Axial Vibration Analysis is shown below:
The inputs are described:
1. Analysis:
Select one analysis at a time as shown below. Once the specific analysis option is selected, the corresponding data are also required.
2. Damping Model:
You can select the damping model to be used in the analysis. You can use either the direct damping, or modal damping, or the combination of both. For forced response analyses including the transient analysis, the modal damping can be specified if the direct damping is not readily available. Details on the damping model are explained in the Modal Damping
