Vibration Analysis for Machine Vibration, Resonance & Fatigue (Compliance & MTBF)
Machine vibrating, resonating, or cracking?
We diagnose the root cause and deliver a verified engineering fix — measured on site, analysed rigorously, then proven by repeat measurement so failures do not return and MTBF is protected.
Proof: On a gas compressor programme, we reduced bearing vibration to well below API 619 limits. The client commented: “This is the lowest vibration we have ever had on one of our products.” Read the case study.
Case studies (engineering evidence)
These projects demonstrate vibration analysis used to identify the governing mechanism, the amplification path (often resonance), and the effectiveness of the fix verified by repeat measurement.

Introduction
Predictive monitoring alone does not resolve vibration problems. Long-term reliability requires understanding and controlling the physical mechanisms that cause vibration, resonance and fatigue.
As independent vibration consultants with nearly 30 years’ experience in vibration and structural dynamics, we apply disciplined measurement, analysis and design to diagnose root causes, validate fixes and deliver compliance across industrial, aerospace, construction and precision environments.
What is vibration analysis?
Vibration analysis is the measurement and interpretation of oscillatory behaviour in machinery and structures to identify faults and failure mechanisms. Analysis of frequency, amplitude and phase allows engineers to distinguish imbalance, misalignment, bearing defects and resonance.
The role of the vibration engineer
Sensors collect data — engineers interpret it. Correct diagnosis depends on instrumentation, placement, operating conditions, structural dynamics and acceptance criteria. The objective is not plots, but decisions that prevent repeat failure.
From vibration analysis to reliability
Lower vibration results in lower cyclic stress, slower fatigue crack initiation and longer service life. This is why vibration limits are embedded in standards such as API 619 — compliance directly supports MTBF and reliability.
If you need independent vibration consultants for failure diagnostics, resonance control or compliance verification, contact us or call 01908 643 433.
