Noise, Vibration, Harshness

Testing Wind Turbine Noise Emissions With LabVIEW and PXI

Carsten Thomsen

"We chose the LabVIEW development environment because of its seamless integration with a wide range of NI data acquisition modules, its signal processing capabilities, and its ability to interface to a variety of digital ports from wind turbine control systems. In addition, the TDMS data format provides a robust, high-performance solution for storing virtually unlimited amounts of high-channel-count data."

Noise, vibration, and harshness (NVH); acoustics; and vibration analysis can help your organization with manufacturing test, R&D development, and design validation. NI systems have been implemented in automotive, aerospace, structural, white goods, transportation, and many other industries. These systems have been used for applications from performing simple in-vehicle dynamics tests to determining jet engine noise sources.

Additional Case Studies

NI offers NVH solutions in a variety of formats. Industrial PCs and PXI systems provide the highest-channel-count solutions, and USB solutions offer an alternative form factor. You also can develop NVH solutions with embedded hardware.
