Noise Testing Software



GN-1100 was developed for tracking analysis of sound & vibration of a rotating object.


It can perform pass-fail judgment and tracking analysis of the each three input signal at the same time (Rev.1, Rev.2, and calculation revolution signal based on Rev.1 and Rev.2).


This software is ideal to use in total inspections including vibration analysis of CVT, and turbines operated in parallel.

Up to 20 steps of measurement patterns can be selected by combinations of three items (acceleration/deceleration/constant speed). Upper/lower-limit rotation speeds and data import interval can be set to each step of each input (Rev1, Rev 2 and calculation revolution).

Noise judgment

Judgment, displaying on the screen, and signal output


1. Sections of judge line:up to 32

2. Judge line setting:up to 32

3. Multi judge function

ORF input & Recalculation function (GN-0100)/ Secondary processing function (GN-0110)

Able to read and recalculate the ORF (ONO SOKKI original format of time-series data) format data. In addition to the recalculation function, following functions are available. Analysis from various viewpoints is enabled

·Multi screen display
·Overlay graph display
·Campbell plot
·Rotational fluctuation analysis

It is effective to improve the measurement by checking resonance and abnormal movement of the work piece. When the offline tracking mode is connected to the DS-3200 series hardware, reanalysis is possible by changing the analysis condition immediately after measurement using the most recently recorded data. Also, reanalysis of the ORF file imported to the following read-only screen is possible in the selected analysis condition.

* GN-0100 is only available for reading and recalculation of ORF file.



Rotating fluctuation analysis display

Added judgment function by P.O.A and crest factor
Useful for abnormality diagnosis of bearing or gear dents.

Characteristic natural frequency peaks seen when they are damaged can be checked.


·Judgment by Partial Overall

The peak becomes large when a bearing or a gear has damage. The damage can be checked by narrowing to specific frequency bands and making judgments using power addition.




· Judgment by Crest factor

Focusing on that the measurement waveform has the characteristic frequency component when damaged, the breakage can be checked by making judgment with peak value/real mean square.


GN link function (GN-0120)

The measurement data and pass-fail judgment of workpiece of the sound/vibration devices can be outputted when the GN-1100 is connected to the device which performs the test of workpiece in the transmission or engine production line. The communication formats are LAN, RS-232C*, DIO*, etc.

* Special order products.


File viewer function(GN-0130)

This function is for data management of the large number of files which has been measured and made judgment by the GN-1100. It can be used for searching the workflow information of measured data, and enables to narrow down the multiple workflow data measured in similar condition to perform overlay comparison or averaging.


The display layout can be customized freely in viewer function. You can make a format as you like.


Dual Rev. tracking function (GN-0140)/ Calculation Rev. tracking function (GN-0150)

This function is for the simultaneous tracking measurement which is standardized the Rev 1/ Rev 2/ calculation revolution in each step.

Calculation revolution can be set by combination of four arithmetic operation buttons, based on Rev1 and Rev2.

To use this function, it is possible to perform tracking analysis which is based on the rotating input and output axes with no correlation or rotating axis which cannot be perform rotating measurement for more detailed workflow checking.


Dent judgment(GN-0160)

Capable of dent judgment during tracking measurement of acceleration/ deceleration.

Presence/ absence of a dent or gear can be checked by obtaining the peak value/ peak rate of every dual revolution and phase difference of peak timing.

1. Dent measurement:Up to 32 pairs

2. Number of rotation axis:Up to 6 axes

3. Reference rotation:Rev1/Rev2

4. Rotation ratio:Rotation speed ratio/gear ratio



Real-time Octave Analysis (GN-0170)

The GN-0170 can make pass/fail judgment of work and equipment by 1/3 octave analysis. This function makes it possible to quantitatively perform "judgment close to the auditory sensation of human" having a characteristic proportional to the frequency component, and supports to build up the human-independent test system.
Also, it can recalculate the optimum threshold using data group judged to be normal in the past, and automatically generate judgment lines.
This function contributes to reduce man-hours in standard management at the time of judgment.





Setting example of judgment line

Statistically processes normality judgment data and automatically generates judgment lines. The value outside the normality range is judged to be abnormal.
* Manual setting is also possible (file import etc.).


Application example
(1)Abnormality inspection of transmission and speed reducer
(2)Abnormality inspection of a motor
(3)Abnormality inspection of an engine
(4)Analysis of low frequency sound
(5)Measurement of equipment noise/ vibration
(6)Measurement of sound pressure characteristics of various acoustic products


Auto sequence function (GN-0180)

You can specify the series of operational commands from setting change to result output, and call them later to perform the same operation repeatedly.
Describing commands promotes efficiency of recalculations, and reduces operation errors.


Offset tracking function (GN-0190)

This function allows tracking analysis of the noise caused by the carrier frequency, which is used to change the frequency driving a gear from an inverter in hybrid automobiles, and the order originated from the carrier frequency.


Grade line function (GN-0200)

In grade line function, grade line is created as the base for comparing and assessing a work by the measured peak values of sound/ vibration in different measurement facilities.

To manage the multiple measurement data in the specification information setting, any specification information can be attached to the measurement data.

This function can be used for mass production workflow grade guideline or data management in the quality control division. It will be able to use for visualizing of the dispersion or quality difference of workflow.





Stress tracking analysis function (GN-0210) NEW

This function analyzes in real time the repeated stress and load behaviors applied when the works are in operation by using detected signal of a strain gauge. Helpful to check the strength and safety.



Analysis of tension and torque by setting calculation channel





Production line quality inspection of unit, such as motor, transmission, and speed reducer.

Abnormality inspection of prototype vehicles and parts incorporated in test equipment.

Strength evaluation of new materials.
  And other various scenes
