How to Use

  1. Select your product category from the dropdown (mechanical components, electronics, software modules, or structural assemblies)
  2. Input design specifications: material properties, tolerance stack-up, operating environment (temperature range, vibration, humidity), and production volume
  3. Define V&V acceptance criteria: defect rate threshold, reliability target (MTBF hours), and confidence level (typically 90% or 95%)
  4. Run uncertainty quantification to map parameter variations against failure modes
  5. Review validation matrix output showing test cases required versus actual test coverage

Worked Example

For an automotive bearing assembly: input bore diameter tolerance ±0.05mm, radial load 5kN, operating speed 3000 rpm, ambient temperature -10°C to +80°C. Simulator calculates fatigue life using Hertzian contact stress (L10 = 15,000 hours at 90% reliability). If production defect rate is 0.3%, the simulator generates 47 test scenarios across 6 failure modes (spalling, fretting, cage wear, misalignment). V&V plan flags that 12 thermal cycling tests and 5 endurance runs at 4500 rpm provide 94% coverage of design space. Validation gap analysis shows missing 3 edge-case combinations requiring additional 40-hour test protocol.

Practical Notes

  1. Cat-filter parameter isolates domain-specific failure databases: use "mechanical" for bearing life calculations, "thermal" for IC package reliability, "structural" for fatigue crack propagation in welds
  2. Tolerance stack-up with 6-sigma assumptions typically reduces margin by 2–4% compared to worst-case stacking; tune confidence intervals to match your supply chain capability
  3. Include production process variability (±1.5σ typical for machined parts, ±3σ for injection molded plastics) in Monte Carlo simulations to avoid optimistic reliability claims
  4. Validation matrix output directly feeds test scheduling; prioritize high-sensitivity parameters identified by Sobol indices to maximize fault detection per test dollar spent
