National Instruments is releasing new NI analysis and signal processing tools for applications in: noise, vibration and harshness (NVH); machine condition monitoring; and audio test. The NI Sound and Vibration Measurement Suite Version 7.0 extends analysis functionality with NI LabVIEW virtual instruments (VIs) for performing psychoacoustic measurements, making it possible for engineers to quickly set up tests to quantify sound quality. Additionally, National Instruments is announcing the NI USB-4432, a portable bus-powered dynamic signal acquisition module for making high-accuracy sound and vibration measurements.
Sound and Vibration Measurement Suite 7.0 supports full-featured sound quality analysis so engineers can ensure high-quality acoustics in their designs. The LabVIEW VIs in the Sound and Vibration Measurement Suite also contain octave analysis, frequency analysis and order tracking for automotive, military and aerospace and mechanical and structural designs. Engineers can quickly and efficiently get their applications started with the configuration-based Sound and Vibration Assistant or with more than 50 ready-to-run LabVIEW example code bases provided in the Sound and Vibration Measurement Suite.
David Nelson, President and Principal Consultant at Nelson Acoustics, says: "Sound quality considerations are becoming increasingly important in the design of products. The LabVIEW sound quality algorithms are easy to implement and well laid out – a very welcome addition to the Sound and Vibration Measurement Suite."
Machine condition monitoring
In addition, the Sound and Vibration Measurement Suite is suitable for machine monitoring, machine health and machine efficiency applications. Engineers can develop applications faster by using examples for tachometer processing, order spectra and waterfall plots. The Sound and Vibration Assistant now includes new machine monitoring displays to quickly configure machine diagnostic utilities. The new displays provide diagnostics for motor balance and shaft position in addition to more traditional order analysis displays.
To properly capture high-frequency, low-amplitude vibrations in the presence of low-frequency, high-amplitude signals, the USB-4432 delivers 108dB of dynamic range. The module consists of four analogue input channels for reading from integral electronics (IEPE) sensors and a fifth channel for tachometer input. The five channels simultaneously acquire at rates up to 102.4kS/s, extending the frequency bandwidth and performing higher-frequency readings than other NI USB systems. In addition, the USB-4432 features configurable AC/DC coupling to allow for a variety of vibration sensors on each channel, making it suitable for a wide range of portable applications such as machine condition monitoring and NVH.
