[SatNews] Sound and vibration specialist, Bruel & Kjaer UK is running a range of practical and theoretical training courses, held at the UK’s head office in Royston, throughout autumn.

The company’s first session, Acoustic & Vibration Introduction for Design & Test Engineers, is a three-day course running from 15th to 17th September. It provides industrial engineers with a thorough understanding of the basic concepts that are important for airborne and structure-borne noise—and vibration in machinery.

Due to production and assembling tolerances, wear and load variation, the moving parts in any rotating machine will sooner or later cause annoying vibrations that eventually lead to breakdowns.

Owners of Brüel & Kjær’s PULSE data analysis system can learn about its latest updates and benefit from hands on training at the PULSE User day course, beginning on  September 22nd. This intensive, two-day session teaches attendees how to get the best from their data acquisition system.

Machine Diagnostics is the PULSE configuration containing the basic tools addressing vibration problems in rotating machines:

• Tachometer 
• FFT Analysis 
• FFT Order Analysis 
• Order Tracking Analysis 
• Signal Enhancement 
• Envelope Analysis 
• Cepstrum Analysis

The tools can be used in runup/down sessions and some can be combined, for example, cepstrum analysis of order spectra or envelope spectra for diagnostics of multiple faults. Extended with PULSE Auxiliary Parameter Logging, all data can be tagged with, for example, temperature, oil pressure, position, wind speed, etc., and all results can be shown versus auxiliary parameters.

All analyses can be performed simultaneously and extended with Data Recorder and PULSE Time File Management. The raw signals can be recorded for subsequent analyses. Time Capture, comprising Short Time Fourier Transform, is the right extension for diagnostics of transient phenomena.

PULSE Two-plane Balancing Consultant is an extension for balancing of rigid rotors.

The final course is Vibration Testing for Engineers, running October 13th to 14th, which offers a practical introduction to the subject of vibration testing. It is designed to meet the needs of engineers new to the subject of vibration testing and acts as a useful refresher course for more experienced users. There is also an optional third day, covering the LDS Laser usb Controller.
