Added value thanks to jBEAM's advanced software technology

jBEAM software technology uses specific codes, algorithms and libraries to help researchers and developers optimize the processing of their measurement data and test results. This technology also includes application-specific calculations, visualizations and routines that make it easy for users to obtain the results they want. This overview shows you jBEAM's software technology along with the optional modules and built-in capabilities.

Video

Different video technologies can be processed to maximize output and usability.

  • GStreamer is an open-source multimedia framework that supports a wide range of video codecs.

  • DirectShow supports all video codes defined on the computer, but is only available for Windows.

Automatic converters are available because 64-bit computer systems no longer support certain video codes (not commonly used outside the automotive sector) . One example is the Indeo format, used for crash testing.
 
 

Fast Fourier Transformation (FFT)

jBEAM includes a very fast algorithm to calculate the Fast Fourier Transformation. Thanks to further development of this algorithm, jBEAM has now a 2n independent algorithm. This allows the use of an FFT-based filter suitable for metrological applications. The time signal is transformed in the frequency domain, folded with the filter characteristic, and then transformed back into the time period. Because these filters have such extreme change rates, almost any filter characteristic can be realized. Appropriate components even allow graphic input of filter characteristics.

 

 

MATLAB wrapper

MATLAB (MATrix LABoratory of Mathworks Inc.) is a software tool used to solve mathematical problems; it includes comprehensive libraries for numerical calculations. jBEAM software technology includes the "MATLAB wrapper" module to run MATLAB algorithms (imported as JAR files) with different datasets, and to visualize the results. The MATLAB wrapper investigates the JAR file and automatically detects all MATLAB algorithms contained in it. The user interactively defines jBEAM channels and values as input parameters for the exported MATLAB algorithms. The results from the MATLAB algorithms are automatically converted into jBEAM data items.

Mechanical stress analysis (strain gages)

As well as conversion of mechanical strains into stresses, a rosette calculation is available that supports both 45° and 60° rosettes. Several special calculations are also available: hole drill 2D, hole drill 3D, and ring kernel.

Engine and turbocharger data

jBEAM software technology enables complete analysis of engine test data, including automatic identification of revolution / manifold pressure test points from continuous time signals. Characteristic matrices are calculated and visualized, either at mathematical level or for presentation in graphic format. Characteristic maps of differences between two tests are also supported. As an added benefit, jBEAM allows interactive customization: manually changeable cursors are used to define cuts through the characteristic maps that can then be calculated and compared. As standard, jBEAM supports combustion engines as well as electric motors in two operating modes (running as motor or generator). Iso-power lines can easily be added to the graphic visualization.

Counting procedure

jBEAM includes a set of 1D and 2D counting algorithms, such as "Statistical frequency" with equidistant or non-equidistant class widths in one or two directions.

The Rainflow algorithm is available for lifetime predictions, with two different options for handling the residue. 1D counting methods derived from the 2D Rainflow matrix are also provided: examples include Rangepair, Level Crossing, Span, or Average Counting.

The range of available counting algorithms also includes Dwell Time, Min-Max Frequency and Reversal Point calculations.

Passive safety (NCAP)

All operations required to calculate passive vehicle safety are available: CFC filtering with different methods (including two-way Butterworth), all HIC, 3 millisecond values, time at level, HCD, and various criteria calculations. All calculations can be used individually or as a complete NCAP analysis, observing the input channel codes for necessary additional filtering.

The forces acting on a crash wall can be visualized in motion picture format, synchronized with high-speed crash videos and all time-based signals.

Safety of railway vehicles (UIC)

The safety and behavior of railway vehicles can be calculated according to UIC 518 and EN 14363. To support complete analysis, a Test Section Generator helps to identify time-based measurements and classify them according to the defined curve segments. Correct results are guaranteed by an automated time shift for the signals, depending on the position of the sensors in the direction of the rail and the actual speed.
