VisAnalyser

It is a powerful program complex intended to record and analyze signals of different dynamic processes. The sources of signals can be different: the data can come from DAQ devices in real-time or from a recorded file. It is possible to analyze the data acquired with RULA devices or imported from other acquisition systems.

Possible applications:

  • Viewing the waveform of the recorded signal;

  • Spectrum graphs: calculation of spectrum density, RMS or amplitude spectrum;

  • Statistical analysis: calculating RMS, median, minimum and maximum values in the preset fragment of time; calculating the absolute acceleration value on 3 axes; calculating standard deviation;

  • Signal integration and double-integration, calculating the absolute value and sigma-clipping;

  • Arithmetic operations: adding, dividing or multiplying a signal by a signal or a constant, subtracting a signal from a signal or a constant;

  • Filtration with FIR or IIR filters. You can specify the filter type: high-pass, low-pass, band-pass, band-stop, and the frequency parameters (cut-off frequencies and attenuation ratio);

  • Shock response spectrum;

  • Waterfall analysis;

  • Data recording;

  • Modal analysis.

Windows integration

VisAnalyser software integrates into any Windows system, starting from Windows 7 and later. To start work, you are to install the program using the installation wizard and run the software.

Data export

If you want to use an analysis function, which is not implemented in VisAnalyser software, there are two possible solutions:

  • export the data into CSV or binary format to view it in Matlab, LabVIEW, etc.;
  • implement your own reading program according to open specifications.

Data analysis

VisAnalyser enables the user to view files of virtually any length. The whole file or any file fragment can be shown on the graphs. 

Choose the file fragment in the special preview area, located at the bottom of the graph window, then move the highlighted zone to quickly display a file fragment at any scale.

To see the numbers, which correspond to the graphical data, you can use special cursors – lines, parallel to Y axis. The coordinate of the intersection with X axis and the value of the signal at the intersection point are shown on each of the cursors. It is also possible to highlight the extreme points on the graphs of any signals.

Spectrum Analysis

The user can calculate power spectrum density of the signal, view the RMS and amplitude spectra.Spectrum analysis can be used for vibration diagnostics of machines and mechanisms, finding the source of vibration, finding the differences in the vibration structure of various technical systems.

For spectrum analysis, you can specify:

  • Window length;
  • Window function – Hann, Hemming, Blackman, Newtall, flat-top, Kaiser, Bohmann, Chebyshev;
  • Averaging type – linear or exponential;
  • Zero offset calculation and subtraction.

Part-Octave Analysis

Using part-octave analysis, you can calculate the octave spectrum with the preset octave part from 1/1 to 1/24 based on FFT calculation or IIR-filters. The results of part-octave analysis can be used for vibration diagnostics of machines and mechanisms, calculating the characteristics of acoustic signal, noise level and vibration level.

Part-Octave Analysis

Statistical Analysis

Using statistical analysis, you can obtain various integrated characteristics of the signal, in particular:

  • RMS;
  • Mean value;
  • Minimum value;
  • Median value;
  • Maximum value;
  • Sigma-clipping value.

Besides, with statistical analysis the user can perform integration and double-integration of the signal – i.e. analyze the displacement of the object using the recording of acceleration.

Statistical Analysis

Editing files

In VisAnalyser you can cut the relevant fragment from the data file and then save it as another file for subsequent analysis

Editing files

Balancing Wizard

A fully functional balancing wizard, which supports one-plane balancing and accepts files of recorded data and values as raw data, makes VisAnalyzer a perfect tool of vibration diagnostics.

Balancing Calculator

VisAnalyser has an embedded balancing calculator for vibration diagnostics, which helps to calculate the value and position of the corrective weight.

The calculator supports both setting and removing the corrective weight.

Online analysis

Online analysis is the analysis of the data acquired from the analog channels of the acquisition systems in real time. It is possible to analyze data from up to 512 channels from different sources.

Data Recording

Online analysis mode has an option of data recording. The maximum duration of the recording is only limited by the PC hard drive capacity.

Data Recording

Waterfall Analysis

Waterfall analysis shows the dependency of the signal from frequency and time simultaneously. This type of analysis is used to study the spectrum structure of the signal in time.

Complex Analysis

The analysis results in the online mode can serve as an input signal for other types of analysis, for example, RMS or spectrum calculation.
