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.
