Finite Element Analysis (FEA) Consultants

Design validation and problem-solving for vibration, resonance and fatigue — correlated to measurement

We use FEA to predict, diagnose and design out failure risks in mechanical systems. Our analysis is closed-loop with measurement (EMA/FRF/ODS) so models reflect reality and solutions are proven by test.

What we do

Core FEA capabilities

  • Static stress/deflection; modal analysis; harmonic response; random vibration (PSD) with sensitivity & margin studies.

  • Correlation & model updating (EMA ↔ FEA): FRF/modal tests inform boundary conditions and material properties.

  • Fatigue & durability: HCF/LCF, welded/bolted joints, notch factors and duty-cycle life prediction.

  • Design verification to ISO/API/BS acceptance criteria with clear pass/fail thresholds.

Where FEA supports design

  • Eliminating resonance and transmissibility in mechanical redesign.

  • Optimising stiffness/damping and interfaces to reduce structure-borne noise.

  • Fixture/constraint realism for qualification and production test setups.

Measurement integration

  • FRF/modal testing, ODS and order tracking to anchor models in reality.

  • Pre/post overlays to evidence improvement and acceptance sign-off.

Standards & qualification

  • MIL-STD-810, RTCA/DO-160, IEC 60068, API 619, ISO 20816/7919.

  • Test planning, instrumentation and execution with QA/QC and data lineage.

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.

FAQs

How do you ensure FEA matches reality?

By correlating to measured FRFs and mode shapes, updating boundary conditions and properties until prediction and test align.

Do you handle redesign as well?

Yes — most projects include design changes to remove resonance, improve margins and meet acceptance criteria.

Will you support qualification testing?

We plan and run vibration/shock/climatic tests and provide compliance evidence for audits and submissions.
