Noise Testing Software

GN-1200シリーズ

This is a function that performs appropriate processing in response to abnormal rotation (such as instantaneous noise) mixed into the rotation signal.

The DS-5000 hardware now supports real-time octave analysis and judgment functions (from Ver. 4.1).

In the GN-0100 OFR input and recalculation function, we have added a statistically assessable general indicator, the standardized kurtosis analysis function, as an analytical means to consider the precision of gear tooth surface processing.

This is a new feature of the GN-0120 GN Link function (LAN). It is a control tool that enables automatic measurement without the need for modifications to the device, allowing even those who are not skilled in programming to easily perform simple automatic measurements. It is effective for measurements in situations such as durability testing and aging.

This function allows for the simultaneous display and overlay comparison of multiple tracking analysis data and recalculation by loading ORF files, as well as secondary processing such as Campbell diagrams and rotational fluctuation analysis. It is possible to quickly confirm any resonance or abnormal behavior occurring in the workpiece, which can be utilized for work improvement.
In the online tracking mode with DS-5000/DS-3200 series hardware connected, it is possible to change the analysis conditions later and perform re-analysis using the data recorded just before. Additionally, in offline mode, ORF files can be imported on the following read-only screen, allowing for re-analysis under any desired analysis conditions.

* The GN-1200 can only perform recalculations using ORF files. 

Optimal for abnormal diagnosis of bearings and gears with characteristic natural frequency peaks when damaged.

The device connects to the GN-1200 to control performance tests on the production line, allowing output of measurement data for sound/vibration of the workpiece and the pass/fail judgment results to the device. Three communication formats are available: LAN format (GN-0120), LAN+DIO format (GN-0240), and RS-232C+DIO format (GN-0240).

*We also accommodate custom requests for communication formats not listed above. For details, please contact our sales office or a nearby retailer.

This is software for managing large data files that have been measured and subjected to pass/fail judgment using the GN-1200. It can be used to search for information on measured work that needs to be confirmed, and to filter data from multiple works measured under similar conditions for overlay comparison and averaging, thereby supporting trend management of the work.

This is a frequently used feature for checking the overall data. Typically, it allows users to view all data except for the components of interest, and by displaying two graphs side by side, it becomes easier to compare differences in test conditions or specimens.

Simultaneous tracking analysis based on rotation 1, rotation 2, and calculated rotation is possible for each step. The calculated rotation settings can be configured using 11 types of functions, arithmetic operations, and coefficients derived from rotation 1 and rotation 2. Up to three channels can be set. By using this feature, it is possible to simultaneously perform tracking analysis based on input and output axes that exhibit uncorrelated rotational movements, as well as rotational axes that cannot be measured, allowing for a more detailed observation of work behavior.

*GN-0140 is limited to rotation 1/rotation 2 only.

GN-0160 Impact Analysis Function:
This function applies envelope processing to the time-domain waveforms of measured vibrations and sound pressure, allowing for the extraction of anomalies occurring at specific cycles by monitoring the peak magnitude/phase (period)/ratio per cycle of those waveforms.
It is effective for confirming the presence or absence of gear impacts and bearing damage. This function can be used not only during measurements at a constant rotational speed but also during measurements while accelerating/decelerating.

GN-0230 Envelope Function:
This function uses the same method as the GN-0160, determining the size of peaks in response to periodic buzzing sounds caused by axis wobble and rotational irregularities.

This is a function that uses 1/3 octave analysis to determine the normality/abnormality of work or equipment. By employing 1/3 octave analysis, which has a proportional characteristic to frequency components, it enables quantitative assessments that are close to human auditory perception, supporting the construction of an inspection system that does not depend on human judgment. Furthermore, by utilizing past data that was classified as normal and performing statistical processing to calculate optimal thresholds, it is equipped with a function to automatically generate judgment lines, thereby assisting in reducing the effort involved in managing judgment standards.

The DS-5000 is scheduled to be supported soon.

Statistical processing of normal judgment data automatically generates judgment lines, identifying outliers as anomalies.
(Manual settings and file loading settings are also possible)

This is a function that allows automatic analysis by describing commands from setting changes to output results.
It can streamline work and reduce operational errors when performing repeated recalculations, leading to a reduction in work time.
Additionally, a feature has been added that allows automatic post-processing analysis when data files are placed in specified locations.
Even in cases where analysis of multiple conditions that cannot be processed with a single license is required, continuous post-analysis and anomaly detection can be performed efficiently.

You can perform tracking analysis of the noise components (carrier noise) that originate from the switching signals (carrier signals) emitted by inverters necessary for driving/control of HV vehicle motors.

This is a function that creates grade lines as indicators for comparing and evaluating peak values measured by different measurement equipment. Additionally, to manage a large amount of measurement data, arbitrary information such as operator, equipment name, and measurement content can be added as specifications. This function can be utilized by the quality control department of a factory for managing variations in work and visualizing quality change points.

This is a function that measures the signal from the strain gauge and analyzes the behavior of the repeated stress and load applied while the work is in operation in real time.
Data acquisition for strength and safety verification is possible.

...can be used in various scenes such as ...

This is a function that calculates the rotational speed difference between a reference rotational speed (pulse) signal and a comparison rotational speed signal from the shaft end, and outputs the torsion amount. Components or units subjected to high load and high torque in the rotational direction may cause shaft damage or abnormal vibrations due to this load. However, by using this function, it is possible to evaluate the torsion amount and obtain data for verifying the durability of components and the presence of abnormalities.
