Vibration Analysis

Data Collection and Analysis

LC Engineering provides general services in vibrational data collection, structural monitoring and analysis. With our extensive knowledge of data logging, LC Engineering has a depth of expertise to collect vibrational data and provide post analysis combined with real solutions.

Our VB8 vibration analyser and Ascent analysis and database logging software are very suited to many vibrational analysis troubleshooting scenarios. The hand held unit allows fast convenient data acquisition via magnetic base accelerometers with capabilities of recording channels simultaneously. Motor, gear and bearing definitions and known fault frequencies can be established, while Cross Channel Phase analysis can be utilised to diagnose machine faults such as misalignment, resonance, soft foot, and looseness. Alarm bands and baseline overalls can be set which can also be indicated on the VB8 while taking recordings. The VB8 can also carryout Demodulation, useful as an early warning device as it detects bearing tones before they are visible in a normal spectrum.

The demodulation spectra can be transferred to Ascent and analysed with the same techniques used for normal spectra (e.g. trend plots, alarms, fault frequencies, bearings, and gears).

Vibrating Screen Testing

LC Engineering has over 10 years experience in troubleshooting, testing and monitoring vibratory screens. We have worked closely with screen manufacturer, Ludowici, to verify and improve their market leading designs.

LC Engineering

  • Can provide monitoring service onsite for troubleshooting or in the workshop for testing and commissioning
  • Have developed our own specialized equipment for vibration and stress monitoring
  • Applies the same principles to other machines subject to vibration, impact and mechanical stress

When data acquired from vibration monitoring is combined with finite element analysis it provides a very powerful tool for better understanding the behaviour of your equipment. Understanding how your equipment behaves will lead to less unplanned maintenance, greater machine availability and lower maintenance costs.
