Introducing Analysis Functions of WCA Pro

In-vehicle Real-Time Noise and Vibration analysis system

Introducing Analysis Functions

FFT Analysis Function
A variety of FFT function analysis is available for Real-Time processing and Post-processing with a time-series data file.

65536 Frame size has enabled frequency analysis at 1/25600.

The Compact WCA provides necessary FFT analysis functions, such as spectrum average function, hammering excitation and transfer function measurement with an exciter for vibration analysis and noise analysis.

The standard CWCA system supports MIMO (Multi-Input Multi-Output) functions, which calculate multiple structural responses caused by multiple excitation forces. A signal generator is available as an option.

Tracking Analysis (Option)
Tracking analysis is available for real time processing or post processing with a time-series data file.The CWCA supports analysis modes such as 2D tracking, which process orders in real time, and 3D tracking, which displays a 3D map. It also provides constant ratio tracking, constant band tracking, time tracking, phase tracking, averaging and smoothing.
In 2D tracking function settings, multi channel setting can be easily carried out using a table format. Arbitrary analysis contents can be defined by setting the main substance unit: order/ frequency, bandwidth unit: order/frequency. Tracking points can be arbitrarily selected using minimum RPM, maximum RPM or average RPM.
The CWCA supports 3D map representation in Campbell plot display mode and color spectrum display mode and order selection using a 3D cursor. In addition, it can process selected orders from a 2D tracking function table.

Real-Time Octave Analysis (optional)
The octave function for digital filter method is available as for real time processing or post processing with a time-series data file.
1/1, 1/3, 1/6 and 1/12 octave analyses are possible. Simultaneous measurements with FFT analysis or tracking analysis are possible.

Please refer to the configurations example for license of off-line analysis software.

Filter Function (Optional)
The CWCA supports Digital filter processing with low pass, high pass, band pass or band reject for post-processing with a time-series data file.

3D post-processing function (included in Tracking function)
Post-processing calculation is available to 3D data (MFU file/ Block data). A variety of calculation functions, such as selection from arbitrary order / frequency data (main substance unit: order/ frequency, bandwidth unite: order/ frequency), 2D data selection from selected RPM or Record, function transformation (converting from spectrum map to Octave map), averaging, weighting, differentiation/ integration, are supported.
