Certification
In 2001 the quality management system of SPC Dynamics was put through facultative certification. In 2016 it was recertified for compliance with standards ISO 9001:2008. Its results confirmed a high level of goods and services quality management. In 2001 the quality management system of SPC Dynamics was put through facultative certification.

Measuring System for Broadband Vibroacoustic Processes

Print

Continuous and sustainable signals recording (without data omission) is a distinctive feature of 3541 measuring module developed by DYNAMICS SPC.

The article is devoted to the module results. The works result is vibration signal sampling of traction motor of electric train and 250 sec duration and 65 kHz sampling frequencies are shown as a spectrogram.

The spectrogram shows two sympathetic vibration zones of vibration sensor used for the signal obtaining. The peaks, frequencies and their levels which do not depend on electric train speed (rotational frequency) and perturbation action availability (available even when the electric train is stopped) are also marked on the spectrogram.

Harmonic components of vibration signal spectrum are in range from 0 to 10 kHz, in speed rage from 0 to 120 km/h. The frequencies of harmonic components vary directly electrical train speed. The zones showing the electric train speed-up and running-out are clearly distinguished on the given data visualization form.

The system based on 3541 module allows executing vibroacoustic and acoustic emission diagnostics in real-time of machinery including machineries in non steady conditions.
