FFT analyzer Frequency analysis Abnormal noise analysis Ono Sokki Thailand

With the expansion of EV manufacturing in Thailand, the demand for new tests is also expected to increase. In this article, we will introduce the solutions of Ono Sokki, which has particular strengths in sound & vibration measurement among measuring instruments, together with Mr. Kumakura of the company's Thai subsidiary.

Measurement to analysis of frequency in sound/vibration, all in one device! Comprehensive FFT analyzer with advanced analysis capabilities

Sound and vibration performance is important in automobile development. It is necessary to suppress noise and vibration from motors and compressors while taking into account fuel efficiency, cruising range, and safety. Abnormal vibration and noise can lead to reduced durability, loss of comfort, and damage to the brand image, so accurate measurements are required during both the development and manufacturing phases.

Ono Sokki offers a wide variety of measuring instruments such as speedometers, flowmeters, torque meters, rotation/dimension meters, etc. In this article, we will focus on sound and vibration measuring instruments, which are our particular focus, and introduce the following two products.

■ FFT analyzer/Sound & vibration analysis system: O-Solution DS-5000 FFT analyzer Frequency analysis Abnormal noise analysis Ono Sokki Thailand

This device can analyze sound and vibration in real time and record the data. It has a wide range of analysis functions, such as investigating the cause of abnormal noise and evaluating sound quality.

＜Features of the O-Solution and DS-5000＞

1. Expandable up to 240 channels

Vibrations at various locations can be recorded simultaneously with multiple channels.

３．filter function for quick identification of abnormalities

While playing back the recorded sound, filtering can be applied to quickly extract only abnormal noises. This leads to quick identification and investigation of the cause of the subnormal noise.

４．Battery-powered, portable, and PC-less operation

The DS-5000 can record high-precision data even in locations where PC operation is difficult or power supply is unavailable, such as during driving tests. In addition, it can be operated from a smartphone or tablet.

５．Direct reading of data logger manufacturer's files

The data formats of commonly used logger manufacturers can also be read directly.

It is a product with extensive software and a wide range of capabilities.

"O-Solution is characterized by its ability to easily compare and analyze large volumes of time-series data, and its multifunctionality includes frequency analysis functions such as FFT analysis, tracking analysis, and octave analysis, as well as digital filtering. In addition, the strength of Ono Sokki products is that they provide added value in measurement work by offering smooth execution of real-time measurement and analysis, efficient data management with the Data Manager, and automation of analysis with external control functions. They are widely used in laboratories, R&D, on-sites, and field measurement applications."

■ FFT Comparator/CF4700A

The CF-4700A FFT comparator is a line judge ideal for precise quality inspection of products by sound and vibration. Equipped with the FFT frequency analysis technology that Ono Sokki has cultivated over many years, it extracts problematic and distinctive frequency components and determines the quality, providing an assessment. By identifying the characteristics of defective products with the O-Solution and DS-5000 and by configuring this information in CF-4700, a pass/fail judgment can be made automatically. It streamlines quality control in the manufacturing process and contributes to the delivery of highly reliable products.

Experienced Thai staff provide supports and advices during data measurements and analyses

“Our experienced staff, all of whom have been with us since our establishment in 2006, are still on our team. One of our strengths is that we can provide product lectures and data analysis/analytical advice among Thai people. In addition, as a future initiative, we are preparing to handle maintenance, repairs, and additions of functions for the installed measuring instruments in Thailand. We believe that by being able to address these matters entirely within Thailand, we can reduce the burden on our customers in terms of lead time and cost."

Ono Sokki and Nihon Denkei have a strong cooperative relationship in Japan, and in Thailand, we would like to strengthen our initiatives that only two companies can undertake to help our customers solve their problems.
