Campbell diagram with AMSR

3000.00 €

Campbell diagram is a powerful extension to evaluate modal analysis directly in Ansys Workbench environment. It’s allowed to plot the diagram and detects all the frequencies crossings in user-friendly GUI. This version is equiped with Automatic Mode Shape Recognition (AMSR).


Campbell diagram extension is a built-in tool available directly from Ansys Workbench tree. It gives significantly more options than Ansys offered tool and now is equiped with Automatic Mode Shape Recognition (AMSR).
The most important, the extension does not required calculation for the non-rotating system and nominal rotational speed. The tool creates slopes based on one point of calculation. It might be non-rotating or rotating system. The evaluation of the second slope point is made automatically based on temperature scaling. That approach can save a lot of time.
Campbell diagrams allows calculating average temperature across examined body and specifies the percentage margins for the crossings and defines the excitation data.
The output crossing points are given in tabular data as a frequencies as well rotational velocities. Similar data is available for the specified margins.
The number of natural frequencies can be determined by the user. The tool is easy-to-use, very intuitive  and allows the modification of data in any point.

Automatic Mode Shape Recognition (AMSR) – is our proprietary algorithm based on machine learning to identify the model shape based on the implemented in the tool database. From now on, there is no need to manually evaluate the results and describe the vibration form. Our tool is able to correctly recognize and provide information about the form on a Campbell diagram.
We trained our database on a series of compressor blades. As part of our subscription, we offer to train the algorithm for your specific solutions and needs.


  • Automatic creation of Campbell diagram based on one speed point (0RPM or nominal speed);
  • Possibility to manually enter margins for crossings;
  • The major crossings are given in tabular form;
  • Possibility of manual input of any number of excitation;
  • Easy-to-use even for in experienced users;
  • No need of APDL scripting;
  • Automatic Mode Shape Recognition


Campbell diagram is always a challenging procedure which consume a lot of time. The tool can offer automatically created Campbell diagram based on one point slope. The output gives not only graphical representation of the frequencies and excitation but also the major crossing and margin in tabular form. The approach eliminates any other exterior tools such i.e. Excel etc. Additionally, the Campbell diagram can obtain and include the average bodies temperature what save significant amount of time.
