General NV measurement software for completed vehicles

Ragusa

Automobile manufacturers are focusing on reducing unpleasant sounds as part of their pursuit of comfort, and they are working hard to improve sound quality so that the sounds produced are perceived as pleasant.

Ono Sokki has developed the application software "Ragusa" based on their experience in measuring vehicle noise and vibration gained through joint research and development with automobile manufacturers, following the flow of measurement procedures in the field.

It is a multi-channel software that allows for easy, reliable, and safe data acquisition, and excels in maintainability.

We will respond to the request of the personnel involved in daily operations who want a "user-friendly and stress-free measurement system."

Ragusa is named after the initials of Rational Automobile's Gauge Unified System of Automatic Control.

NV measurement system suitable for bench tests and actual driving tests of completed vehicles.
Simple configuration with the DS-3200 data station (40 kHz) and PC, supporting up to 32 channels.
compact front-end with channel expandability
Operational flow in accordance with daily business procedures (see the figure below)
A condition setting function that can be easily customized by administrators.

This is a dedicated application software ideal for measuring vehicle noise and vibration.
We offer a lineup of software tailored to your needs.

Rotational tracking is most commonly used for measuring noise and vibration generated by rotating bodies. This is because the excitation force depends on the rotational speed. Measuring the relationship between that excitation force and the natural frequency of the rotating body is what rotational tracking measurement entails.
There are modes for executing measurements that follow changes in rotational speed separately from modes that execute measurements of specific analysis bands according to the rotational speed, as well as modes that execute both simultaneously, allowing for detailed measurements with simple operations.

It is possible to select the measurement mode from external sampling frequency, internal sampling frequency, internal sampling count, and simultaneous internal and external sampling.
Simultaneous real-time display of tracking waveforms (up to 4 screens) and frequency (or order) spectrum during measurement.
Computational functions for up to 10 measurements each for acceleration and deceleration (maximum, minimum, average).

It is used to quickly identify the main causes of noise and vibration problems and to solve these issues. Through measurements primarily based on spectral analysis using FFT, it becomes possible to obtain information that cannot be derived from time-domain signals (data). Furthermore, by comparing previously measured data, it is also possible to quantitatively grasp the effects of improvements.
