Case Studies — Noise, Vibration & Structural Dynamics

Real-world projects where precision measurement, rigorous analysis, and practical design deliver proven results.

Investigate Test & Measure Analyse Design Support

Our Process: From Problem to Proven Solution

From acquisition to analysis — accuracy starts with the engineer who captures the data. With over 30 years of measurement and engineering experience, our approach is structured yet adaptable: some projects run linearly; others loop back to refine understanding. Every stage builds toward one goal — a solution proven to work in practice.

Investigate — understand the challenge, context and what “good” looks like; agree success criteria.
Test & Measure — deliberate, disciplined measurements (vibration, modal, FRFs) captured by the same engineer who will analyse them.
Analyse — turn measured data into actionable insight using FEA, EMA and model updating to identify root causes.
Design — engineer a robust, practical solution validated in analysis and grounded in data.
Support — implement, verify against criteria and provide in-service assurance.

Prevention of Structure-Borne Sound

Night-time vibration noise from a rooftop installation disturbed residents. Identifying a 58 Hz source and installing isolation removed the problem and preserved the tower’s function.

Category: Noise & Vibration
Techniques: FFT analysis, vibration monitoring, isolation

Vibration Case Studies

Solving Vibration Issues at a Quarry Plant

Severe vibration made operations unsafe. FEA, EMA and correctly specified AV mounts eliminated resonance and restored stable operation.

Category: Vibration
Techniques: FEA, EMA, isolation design

API 619 Vibration Compliance

A compressor frame resonated near a 47.2 Hz pulsation frequency, breaching API 619 limits. Frame stiffening, validated by FEA and FRFs, shifted the natural frequency and achieved compliance.

Category: Vibration
Techniques: FEA (Ansys), FRFs, modal testing
