Noise testing software

GN-1200シリーズ

This function performs appropriate processing when abnormal rotation (such as momentary noise) is mixed into the rotation signal.

Real-time octave analysis and judgment function can be used even when connected to the DS-5000 (GN-0170).
Real-time octave analysis and judgment functions are now available on the DS-5000 hardware. (Available from Ver. 4.1)

The GN-0100 OFR input and recalculation function now includes a kurtosis analysis function, a standardized and statistically applicable indicator, which is used as an analytical tool to consider the machining accuracy of gear teeth.

GN-0120 is a new feature of the GN Link function (LAN). It is a control tool that enables automatic measurement without requiring any modifications to the device, and even those who are not comfortable with programming can use this tool to perform simple automatic measurements. It is effective for measurements in various situations, such as during durability testing or aging.

This function allows you to read ORF files, perform recalculations, simultaneously display and overlay multiple tracking analysis data, and perform secondary processing such as Campbell plots and rotational variation analysis. It enables you to quickly identify resonances and abnormal behavior occurring in the workpiece, which can be used for workpiece improvement.
In online tracking mode with connected hardware in the DS-5000/DS-3200 series, it is possible to change the analysis conditions later and re-analyze using the data recorded immediately before. In offline mode, ORF files can be imported using the read-only screen shown below, and re-analysis can be performed under any analysis conditions.

* The GN-1200 can only recalculate by reading ORF files. 

Ideal for diagnosing abnormalities in bearings and gear impact marks that exhibit characteristic intrinsic frequency peaks when damaged.

The GN-1200 can be connected to and controlled by equipment used for performance testing of workpieces on the production line. Measurement data of sound/vibration of workpieces and equipment, as well as the results of workpiece pass/fail judgment, can be output to the equipment. Three communication formats are available: LAN format (GN-0120), LAN+DIO format (GN-0240), and RS-232C+DIO format (GN-0240).

*We can also accommodate custom orders for communication formats other than those listed above. For details, please contact our sales office or your nearest dealer.

This software manages large amounts of data files previously measured and pass/fail judgment by the GN-1200. It allows you to search for information on measured workpieces, narrow down data to multiple workpieces measured under similar conditions, and perform overlay comparisons or average calculations, supporting trend management of workpieces.

This is a frequently used function for reviewing the entire dataset. Typically, it allows you to view all data except for the component you are interested in, and by displaying two graphs side-by-side, it becomes easier to compare differences in test conditions and test specimens.

Simultaneous tracking analysis based on Rotation 1/Rotation 2/Calculated Rotation is possible for each step. Calculated rotation settings can be configured using 11 types of functions, arithmetic operations, and coefficients from Rotation 1 and Rotation 2. Up to 3 channels can be configured. This function allows for simultaneous tracking analysis based on input and output axes with uncorrelated rotational movements, or rotation axes that cannot be measured, enabling a more detailed examination of workpiece behavior.

*GN-0140 is only available in rotation 1/rotation 2.

GN-0160 Impact Analysis Function:
This function applies envelope processing to the time-domain waveforms of measured vibrations and sound pressure, and by monitoring the peak magnitude/phase (period)/ratio of each period in the waveform, it is possible to extract anomalies that occur at specific periods.
This function is effective for checking for dents on gears, scratches on bearings, and other damage. This function can be used not only for measurements at a constant rotational speed, but also during acceleration and deceleration.

GN-0230 Envelope function:
This function uses the same method as the GN-0160 to determine the presence of periodic humming noises caused by axial wobble or rotational irregularities based on the magnitude of the peak.

This function uses 1/3 octave analysis to determine whether workpieces and equipment are normal or abnormal. By utilizing the geometrically uniform characteristics of 1/3 octave analysis with respect to frequency components, it enables quantitative judgments that closely resemble human hearing, supporting the construction of inspection systems that are not dependent on human judgment. Furthermore, by incorporating a function that calculates the optimal threshold using statistical processing based on previously determined normal data and automatically generates a judgment line, it helps reduce the effort required for managing judgment standards.

*DS-5000 support is planned for the near future.

The system statistically processes normal data to automatically generate a judgment line, and identifies outliers as abnormal.
(Manual settings and settings can also be configured by importing a file.)

This feature allows for automated analysis by describing the actions from setting changes to result output using commands.
When recalculations are performed repeatedly, this can streamline the process, reduce operational errors, and ultimately lead to a reduction in working time.
Furthermore, a new feature has been added that allows for automatic post-processing analysis once the data files are placed in a specified location.
Even when analysis of multiple conditions that cannot be handled with a single license is required, efficient sequential post-analysis and anomaly detection can be performed.

This software allows for tracking analysis of noise components (carrier noise) originating from the switching signal (carrier signal) emitted by the inverter necessary for driving/controlling motors in hybrid vehicles.

This function creates grade lines as an index for comparing and evaluating peak values measured with different measuring equipment. Furthermore, to manage a large amount of measurement data, arbitrary information such as operator/equipment name/measurement details can be added as specifications. This function can be used by factory quality control departments to manage workpiece variations and visualize points of quality change.

This function measures strain gauge signals and allows for real-time analysis of the behavior of repeated stresses and loads applied to a workpiece while it is in operation.
It is possible to acquire data for strength and safety verification.

...and can be used in a variety of situations.

This function calculates the rotational speed difference from a reference rotational speed (pulse) signal and the rotational speed signal of a comparison shaft end, and outputs the amount of shaft torsion. Parts or units subjected to high load and high torque in the rotational direction may experience shaft damage or abnormal vibration due to that load. By using this function, you can obtain data to evaluate the amount of torsion and verify the durability and presence of abnormalities in the parts.
