Modeling/Data Editor

Before building the model, it is important to know the coordinate system. Z-axis is the spinning axis in DyRoBeS. The lateral vibration of the discretized system is described by two translational (x, y) and two rotational coordinates at each finite element station. For torsional vibration, the motion of each finite element station is described by a rotational displacement about the spinning axis. For axial vibration, the motion of each finite element station is described by a translational displacement (z) along the spinning axis.

A number of folders, as shown below, with different tabs are provided in the Data Editor and you can enter your rotor bearing system data accordingly. The description for each folder will be explained in the following sessions.

There are more tabs (buttons) under the Torsional/Axial Tab as shown below.

Since the same data file can be used in the lateral, torsional, and axial vibrations, data in the irrelevant folder will not be used in a particular analysis. The usage of the data folder is listed below for reference.

Data Utilization for Lateral, Torsional, and Axial Analysis

It should be noted that the same model will be used in lateral, torsional, and axial analyses, even though some of the inputs are not required for certain analyses and these entries will be ignored.

Since saving data is just a click on the Save button, it is a good practice to save your data from time to time to prevent any data loss. If you wish to save a different model without changing the original data, use Save As to save the data into another file,
