Analysing sound and vibration measurements
19/07/2022
The imc WAVE 2022 has been introduced by imc Test & Measurement, which the company claims is a powerful piece of software for standard-compliant noise and vibration analysis with imc data acquisition systems.
Consisting of four analysers, it offers a comprehensive range of analysis functions for sound pressure and sound power measurement, structural analysis and the analysis of vibrations and of rotating machines. The software guides users from configuration to calibration and measurement to professional report in just a few steps, reducing set-up time and delivering reliable results for less experienced users in the field of noise, vibration and harshness (NVH). Typical applications can be found in mobile or stationary set-ups: testing of prototypes, machine monitoring and test stands for development or end of line.
Microphone signals are processed simultaneously and sound level, sound pressure and sound power are determined online according to the relevant standards. The imc WAVE noise analyser offers a comprehensive set of functions for this purpose, such as fast Fourier transform (FFT) and octave or third octave spectra as 2D or 3D diagrams (waterfall). Furthermore, microphones can be calibrated within the analyser.
Vibrations in machine monitoring and diagnostics can be analysed using imc WAVE vibration; it provides advanced evaluation tools for characteristic parameters according to established standards and evaluates data online during the operation of rotating machines. Based on speed calculations from pulse signals, it transforms signals to angle domain and displays the vibration process as an order spectrum.
The imc WAVE structure determines structural dynamics problems in components; it calculates transmission functions and resonance frequencies in order to analyse the vibration behaviour, bending and torsional stiffness.
It also pursues a comprehensive approach in analysing the origins, propagation paths and effects of noise or vibrations. In addition to sound and vibration signals, it also incorporates other physical measurement variables, such as speed, force, pressure, temperature or digital fieldbus data.
The imc WAVE 2022 works seamlessly with all imc data acquisition systems. Its components can also be integrated directly into the imc STUDIO measurement software platform to equip automated test benches with NVH functionality.
