Maintenance and repair

Vibration analysis and diagnosis

Excessive mechanical vibration can lead to various types of problems such as energy loss, quality defects, working environment problems and reduced production speed. In the worst case scenario, these problems can lead to malfunctions, which can result in accidents and unplanned downtime.

Structural vibration analysis

In order to be able to take appropriate measures to prevent excessive vibration, it is necessary to understand the vibration characteristics of the machine.

Structural vibration analysis services include Operational Deflection Shapes (ODS) analysis and modal analysis. By measuring the motion of a machine under existing operating conditions, we are able to understand how individual points on the machine move (amplitude and phase) and define the machine's motion pattern.

While performing the measurements, we use the multi-channel equipment in combination with tools for data visualisation, animation, analysis and documentation for simultaneous data collection. This provides an understanding of the machine's motion patterns and the causes of unexpected vibrations.

The following measurements and activities are typically performed:
  • Visual inspection of equipment and structures
  • Initial data collection (spectrum, time and phase)
  • Vibration data analysis
  • In some cases, transient vibration data collection
  • Machine design and structural evaluation
  • Numerical simulation model development
  • ODS vibration data collection
  • ODS data animation
  • Additional measurements and analyses
  • Presentation and description of conclusions and recommendations from structural vibration analyses
Remote diagnostic services

The benefits of condition-based and predictive maintenance programmes are widely recognised today. However, realising the full commercial value of equipment performance can be a complex and costly process.
