RogaANA - Modal Analysis
To perform a modal analysis for a structure transfer functions retrieved from a measurement are needed which are generated by the RogaANA Signal Analysis module. Modal values like modal vector, modal frequency and attenuation are determined offline with RogaANA Modal Analysis. It allows importing transfer functions and geometric data.

Structural modifications with
RogaANA Modal Analysis (Offline Processing)
After finishing a modal analysis often the question arises how to change a structure in a way where the specified properties are get without spending too much effort. This is possible with an offline simulation with the structure in question.
Sensitivity Analysis
At first a sensitivity analysis is performed. It shows in a list for all modal vectors any detected points of the structure where the topmost sensitivity for changes of mass, stiffness and/or attenuation is given. Additionally for any modal vector the complete analysis can be output.
Structural Modification
After the points (measurement points) are selected where changes shall occur and the items to change (additional mass, additional stiffing, and/or additional attenuations) are defined the modal frequencies are computed anew. For the computation the assumption is made, that any modal vectors known of the
modal analysis remain unchanged the same.
The first result is a table which contains the old and the new modal values. A comparison of modal frequencies and attenuations allows to determine if the changes made for the simulation were sufficient or not.
The second result is a representation of the new computed transfer function (green graph) for any measurement point of the modified system together with the measured transfer function (blue graph) and the fit graph (red graph). The presentation shows the influence of the actual changes.
RogaANA - Operational Deflection Shape Analysis
To perform an operational deflection shape analysis of a structure in a certain frequency range transmissibilities and auto power spectra are needed which were
measured and stored with RogaANA Signal Analysis software. Determining excitation frequencies and operational deflection shapes is possible offline.
Even more, transmissibilities, auto power spectra, and geometric data can be imported in UFF format to achieve operational deflection shape analysis.

Acoustic Camera
Acoustic cameras allow to make noise visible. Therefore noise sources and generated frequencies can be recognized. Theorem of acoustical camera:
Seeing with ears means to make visible what could be heard.
Acoustical cameras consist of
- an array of microphones
- a measurement amplifier
- a measurement computing device
- an analysis program
- a digital (optical) camera
Noise is acquisited with microphones and presented as a colored topological diagram after a special type of analysis was performed. The type of colored topological diagram is well known
in other areas like noise intensity measurement, order analysis, and so on.
