# CONTEXT.md — Hydrotech Beam Structural Optimization
|
||
|
||
## Client
|
||
Hydrotech (internal test fixture)
|
||
|
||
## Objective
|
||
Minimize beam mass while reducing tip displacement and keeping stress within limits. Multi-objective: lighter, stiffer, safe.
|
||
|
||
## Key Parameters
|
||
| Parameter | Current | Range | Units | Notes |
|
||
|-----------|---------|-------|-------|-------|
|
||
| beam_half_core_thickness | 20 | 10–40 | mm | Core half-thickness |
|
||
| beam_face_thickness | 20 | 10–40 | mm | Face sheet thickness |
|
||
| holes_diameter | 300 | 150–450 | mm | Lightening hole diameter |
|
||
| hole_count | 10 | 5–15 | integer | Number of lightening holes |
|
||
|
||
## Constraints
|
||
- Max tip displacement: < 10 mm
|
||
- Max von Mises stress: < ~130 MPa (steel, conservative)
|
||
- Mass tracked via NX expression `p173`
|
||
|
||
## Objectives
|
||
- Minimize mass (currently ~974 kg — way too heavy)
|
||
- Minimize tip displacement (currently ~22 mm, target < 10 mm)
|
||
- Keep stress reasonable (steel, margin exists)
|
||
|
||
## Baseline Performance
|
||
- Mass: ~974 kg
|
||
- Tip displacement: ~22 mm
|
||
- Material: Steel (AISI)
|
||
|
||
## Model
|
||
- NX Part: `Beam.prt`
|
||
- FEM: `Beam_fem1.fem`
|
||
- Idealized part: `Beam_fem1_i.prt`
|
||
- Simulation: `Beam_sim1.sim`
|
||
- Solver: NX Nastran (static structural)
|
||
- Analysis: Static structural
|
