# Bracket Stress Minimization Study
|
|
|
|
## Overview
|
|
|
|
This study optimizes a structural bracket to minimize maximum von Mises stress while maintaining displacement constraints.
|
|
|
|
## Objective
|
|
|
|
Minimize maximum von Mises stress in the bracket under applied loading conditions.
|
|
|
|
## Design Variables
|
|
|
|
- **tip_thickness**: 15.0 - 25.0 mm
|
|
- Controls the thickness of the bracket tip
|
|
- Directly affects stress distribution and structural rigidity
|
|
|
|
- **support_angle**: 20.0 - 40.0 degrees
|
|
- Controls the angle of the support structure
|
|
- Affects load path and stress concentration
|
|
|
|
## Constraints
|
|
|
|
- **Maximum displacement** ≤ 1.0 mm
|
|
- Ensures the bracket maintains acceptable deformation under load
|
|
- Prevents excessive deflection that could affect functionality
|
|
|
|
## Model Information
|
|
|
|
All FEA files are located in [model/](model/):
|
|
- **Part**: [Bracket.prt](model/Bracket.prt)
|
|
- **Simulation**: [Bracket_sim1.sim](model/Bracket_sim1.sim)
|
|
- **FEM**: [Bracket_fem1.fem](model/Bracket_fem1.fem)
|
|
|
|
## Optimization Settings
|
|
|
|
- **Sampler**: TPE (Tree-structured Parzen Estimator)
|
|
- **Total trials**: 50
|
|
- **Startup trials**: 20 (random sampling for initial exploration)
|
|
- **TPE candidates**: 24
|
|

## Running the Optimization
|
|
|
|
From the project root:
|
|
|
|
```bash
|
|
python run_5trial_test.py # Quick 5-trial test
|
|
```
|
|
|
|
Or for the full optimization:
|
|
|
|
```python
|
|
from pathlib import Path
|
|
from optimization_engine.runner import OptimizationRunner
|
|
|
|
config_path = Path("studies/bracket_stress_minimization/optimization_config_stress_displacement.json")
|
|
runner = OptimizationRunner(
|
|
config_path=config_path,
|
|
model_updater=bracket_model_updater,
|
|
simulation_runner=bracket_simulation_runner,
|
|
result_extractors={...}
|
|
)
|
|
|
|
study = runner.run(study_name="bracket_study", n_trials=50)
|
|
```
|
|
|
|
## Results
|
|

|
|
|
- **trial_logs/**: Detailed logs for each trial iteration
|
|

|
|
- **history.csv**: Results in CSV format for analysis
|
|

|
|
- Stress values in MPa, displacement in mm
