Исследования и разработки продукции
Измерение, разработка, поиск и устранение неисправностей, документирование шума и вибрации в продуктах и компонентах, от точечного тестирования в режиме реального времени до анализа данных и постобработки
Smaller companies, companies with limited R&D resources, and companies and departments where sound and vibration measurement and analysis is not part of the core business are sometimes met with requirements in regards to sound and vibration. This can be documentation or verification of product noise levels, analysis of basic structural properties or troubleshooting unwanted noise or vibration.
To be able to conduct these measurements easily and professionally, a system that is simple to set up and use is preferred. Two measurement channels is often enough. The measurement and analysis software interface needs to be intuitive to aid the infrequent or inexpert user, while delivering confidence that the results are correct.
For occasional measurement on components and products in the lab or in the field, we recommend Photon+, an all-in-one portable analyzer for sound and vibration. Data recording and verification is set up and run from a simple PC software interface, and the accompanying software package gives a range of analysis capabilities, including dynamic signal analysis, modal testing, acoustic analysis and rotating machinery diagnosis and analysis.
Field measurements are often complicated to plan, have short time windows and are difficult to reproduce, should something go wrong. Hence, it is essential that the recorded data from field measurements, for example from road testing a vehicle or validating a pump, is of high quality and complete.
For doing time data recording and validation in the field, and conducting simple benchmarking, troubleshooting and analysis tasks such as FFT, order analysis, spectrogram analysis, sound quality metrics, narrowband and synthesised 1/3-octave band analysis, we recommend using a Sonoscout-based system.
The Sonoscout system is a combination of an iPad app and a battery-powered acquisition front end based on a LAN-XI data acquisition module. This can be placed anywhere and connects up to 12 measurement transducers, from which it transmits data wirelessly to the app for recording. A binaural microphone headset captures ambient sound in real-time and replays recordings immediately. The Sonoscout app continuously displays test information, to maximize confidence during testing, and brings simple control and analysis to tasks such as comparing data sets. For further analysis, data can be exported into BK Connect or other post-processing software
