The development of energy-efficient electric vehicles (xEVs) is accelerating globally, and there is a growing demand for higher performance and efficiency in key components such as large drive motors, various small motors, gearboxes including reduction gears, and e-axles that combine these components.
GN-1100 Ver.2.5 leverages the diverse measurement and analysis, high-speed signal processing, and automatic judgment technologies cultivated through 100% inspection for noise and vibration abnormalities in transmission production sites, and now enhances its functions and performance to meet the demands of abnormality inspection for rotating equipment such as motors and speed reducers.
We have enhanced the functions of torsional vibration analysis, frequency response waveform analysis, specific period sound detection, disturbance removal in stress tracking analysis, and 1/3 octave determination, and further pursued practical productivity improvements through usability improvements incorporating feedback from production line sites.
GN-0220 Torsional vibration calculation function (new option)
This function calculates the rotational speed difference from the rotational speed (pulse) signal of a reference axis and the rotational speed signal from the end of a comparison axis, and outputs the amount of shaft torsion. Parts or units subjected to high load and high torque in the rotational direction may experience abnormalities such as shaft damage or abnormal noise due to the 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.
GN-0230 Envelope Analysis Function (New Option)
This function applies envelope processing to the time-domain waveforms of measured vibrations and sound pressure, and by monitoring the peak magnitude, phase (period), and ratio for each period of 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-1100 Noise Testing Software (Version Upgrade)
- To address measurement errors caused by individual differences in workpieces or incorrect sensor installation, a function to set upper and lower threshold limits based on the analyzed waveform has been added.
- Added a function to output a CSV file with the judgment results.
GN-0210 Stress Tracking Analysis Function (Version Upgrade)
- An envelope filter has been added as a noise reduction function for strain gauge signals, which are susceptible to noise.
- Added a setting to use all measurement data points within a single block when calculating the average maximum/minimum values.
