NI recently introduced a new version of its analysis and signal processing tool, NI Sound and Vibration Measurement Suite 7.0, which can be applied to noise, vibration and smoothness (NVH) testing, machine condition monitoring and audio testing applications. It combines NI LabVIEW VI to expand the analysis function, can effectively test the sound quality, help engineers quickly build the system, test the sound quality. In addition, NI introduced NI USB-4432, which is a portable bus-powered dynamic signal acquisition module that can be applied to high-precision sound and vibration testing.
Version 7.0 of the NI Sound and Vibration Measurement Suite supports full sound quality analysis, which provides engineers with a guarantee for designing systems with high quality sound quality. The LabVIEW VIs in the kit also include the octave analysis, frequency analysis, and order tracking functions required for mechanical and structural design applications for automotive, military, aerospace, mechanical, and structural design applications. With more than 50 ready-to-run LabVIEW sample codes provided in the configuration-based sound and vibration measurement assistant or kit, engineers can start application development quickly and efficiently.
"The sound quality factor has become more and more important in product design. The LabVIEW sound signal processing algorithm is convenient and easy to use, and it can complement each other with the sound and vibration measurement suite."-

In addition, sound and vibration measurement kits are ideal for machine monitoring, machine health and efficiency applications. By using sample code, engineers can more quickly develop applications for tachometer signal processing, order analysis, and waterfall chart display. The newly introduced sound and vibration measurement assistant introduces a new machine monitoring configuration interface, which can quickly configure machine diagnostic equipment. In addition to providing the functions of the traditional configuration interface, the new configuration interface can also perform motor balance diagnosis and shaft positioning.
USB-4432 provides a dynamic range of 108dB, which enables it to accurately capture high-frequency, low-amplitude vibration information in low-frequency, high-amplitude signals. The module contains 4 analog input channels that can collect the output of the IEPE sensor and one channel for the tachometer input. These five channels can simultaneously collect data at a rate of up to 102.4kS / s. Compared with other USB solutions, USB-4432 can provide a higher frequency reading speed. In addition, USB-4432 has a configurable AC / DC input coupler, which allows each channel to be connected to various types of vibration sensors, making it ideal for many portable applications (such as machine condition monitoring and NVH).
