Hydrotech Beam — Structural Optimization
Client: Hydrotech (internal test fixture) Channel: #project-hydrotech-beam Created: 2026-02-08 Status: Technical Breakdown Complete — Awaiting Gap Resolution
Objective
Optimize a sandwich I-beam with lightening holes: minimize mass while meeting stiffness and strength constraints.
Key Numbers
| Metric | Baseline | Target |
|---|---|---|
| Mass | ~974 kg | Minimize |
| Tip displacement | ~22 mm | ≤ 10 mm |
| Von Mises stress | TBD | ≤ 130 MPa |
Design Variables
| Variable | Range | Type |
|---|---|---|
| Half-core thickness | 10–40 mm | Continuous |
| Face thickness | 10–40 mm | Continuous |
| Hole diameter | 150–450 mm | Continuous |
| Hole count | 5–15 | Integer |
Approach
Two-phase optimization:
- DoE (LHS, 40–50 trials) — map the landscape
- TPE (Bayesian, 60–100 trials) — converge to optimum
Total budget: ~100–150 NX evaluations, est. 2–5 hours compute.
