Our proven process
Investigate → Test → Analyse → Design → Support
This is how we deliver outcomes reliably: we identify the mechanism, gather evidence-grade data, analyse what’s really driving the response,
engineer the fix, and then support implementation and verification so the project reaches sign-off.
Investigate the problem context: symptoms, duty cycle, interfaces, constraints, history and acceptance criteria.
Test where uncertainty matters: vibration measurement, EMA/FRF/ODS, strain, operating data.
Analyse the mechanism and margins. FEA sits here to predict stress/deflection and dynamic response, and to test “what-if” design options quickly.
Design the change: stiffness/damping/interface updates, mount/isolation strategy, practical detailing.
Support implementation and verification: reviews, iteration, pre/post overlays, evidence packs and close-out for acceptance.
In practice: measure → model → change → verify. The final step (Support) is what completes the project.
Why choose us for FEA?
-
FEA that drives decisions (not just plots)
We scope the analysis around the decision you need to make: remove resonance, stop cracking, increase fatigue life,
verify a design margin, or demonstrate acceptance against defined criteria.
-
Closed-loop with measurement
Where outcomes depend on realism (especially dynamics and joints), we anchor models with measured behaviour using
EMA / FRF / ODS so boundary conditions and assumptions reflect reality.
-
Support through implementation and sign-off
The job is not complete when the model runs. We support design change, implementation and verification so the solution
is proven by test/measurement and the project closes cleanly.
What is FEA used for (in real projects)?
FEA predicts stress, deflection and dynamic response before you build — and diagnoses the mechanism when something is already failing.
In vibration and durability problems, it is especially effective when used with measured data to confirm the excitation, the transmission path,
and the structural amplification (resonance).
Vibration & resonance: natural frequencies, mode shapes, transmissibility and forced response.
Fatigue & cracking: hot spots, stress ranges, joint features, duty-cycle life prediction.
Design verification: stiffness, margins and pass/fail evidence to acceptance criteria.
In our process, FEA sits within Analyse — and it is made valuable by Support through implementation and verification.
What we do (FEA capability)
-
Core structural & dynamics analysis
Static stress/deflection, modal analysis, harmonic response and random vibration (PSD) with sensitivity and margin studies.
-
Correlation & model updating (EMA ↔ FEA)
FRF/modal tests inform boundary conditions and selected properties so predictions align with real behaviour.
-
Fatigue & durability
HCF/LCF, welded/bolted joints, notch sensitivity and duty-cycle life prediction to reduce failure risk.
-
Design verification to acceptance criteria
ISO/API/BS and client-defined requirements, with clear pass/fail thresholds and defensible assumptions.
Measurement integration (making FEA match reality)
FRF / modal testing to anchor boundary conditions and validate mode shapes and frequencies.
ODS to visualise operating deformation and identify amplification mechanisms.
Order tracking where speed-related excitations drive resonance risk.
Pre/post overlays to evidence improvement and support acceptance sign-off.
Standards & qualification
MIL-STD-810, RTCA DO-160, IEC 60068, API 619, ISO 20816 / ISO 7919.
Test planning, instrumentation and execution with QA/QC and data lineage where required for audits and submissions.
Representative outcomes
API 619 compressor frame — stiffness re-engineering, resonance removed, compliance achieved.
Oil pan resonance — mode separation via FEA; durability improved.
Semiconductor plinth — VC-D micro-vibration performance verified.
Transport shock isolation — SRS-driven design protecting high-value assets.
Case Study Examples
If you tell us the asset type and symptom (cracking, resonance, compliance failure, etc.), we’ll point you to the closest relevant case study.
FAQs
How do you ensure FEA matches reality?
By correlating to measured FRFs and mode shapes where it matters, and updating boundary conditions and selected properties until prediction and test align
sufficiently for a decision-grade outcome.
Do you handle redesign as well?
Yes — most projects include design changes to remove resonance, improve margins and meet acceptance criteria,
with support through implementation and verification.
Will you support qualification testing?
Yes. We plan and run vibration/shock/climatic tests and provide compliance evidence for audits and submissions.
