### 5.1 whiffle_min (Whiffle Tree Minimum Parameter)
|
||||
|
||||
- **Trend**: Optimal values cluster around **47-50 mm** (upper half of range)
|
||||
- **Baseline**: 40.55 mm was suboptimal
|
||||
- **Recommendation**: Increase whiffle_min to ~49 mm for best performance
|
||||
|
||||
### 5.2 whiffle_outer_to_vertical (Outer Support Angle)
|
||||
|
||||
- **Trend**: Optimal range spans **71.6° to 76.5°**
|
||||
- **Baseline**: 75.67° was near the upper optimal bound
|
||||
- **Recommendation**: Maintain flexibility; angle has moderate sensitivity
|
||||
|
||||
### 5.3 inner_circular_rib_dia (Inner Rib Diameter)
|
||||
|
||||
- **Trend**: Optimal values range from **497-524 mm** (lower half of range)
|
||||
- **Baseline**: 534 mm was slightly high
|
||||
- **Recommendation**: Reduce rib diameter to ~500-510 mm

## 7. Recommendations
|
||||
|
||||
### 7.1 Recommended Production Configuration
|
||||
|
||||
Based on the optimization results, the recommended design parameters are:
|
||||
|
||||
| Parameter | Recommended Value | Tolerance |
|
||||
|-----------|-------------------|-----------|
|
||||
| whiffle_min | **49.4 mm** | ±2 mm |
|
||||
| whiffle_outer_to_vertical | **71.6° - 74.1°** | ±2° |
|
||||
| inner_circular_rib_dia | **500 - 520 mm** | ±20 mm |
|
||||
|
||||
### 7.2 Performance Expectations
|
||||
|
||||
With the optimized configuration, expect:
|
||||
- **6.1 nm RMS** wavefront error change from 20° to 40° elevation
|
||||
- **14.4 nm RMS** wavefront error change from 20° to 60° elevation
|
||||
- **30.5 nm RMS** optician workload at 90° orientation
|
||||
|
||||
### 7.3 Next Steps
|
||||
|
||||
1. **Validate with FEA**: Run confirmation analysis at recommended parameters
|
||||
2. **Manufacturing Review**: Verify proposed geometry is manufacturable
|
||||
3. **Sensitivity Analysis**: Explore parameter tolerances more thoroughly
|
||||
4. **Extended Optimization**: Consider enabling additional design variables for further improvement

## 8. Technical Notes
|
||||
|
||||
### 8.1 Zernike Analysis
|
||||
|
||||
- **Number of modes**: 50 (Noll indexing)
|
||||
- **Filtered modes**: J1-J4 excluded (piston, tip, tilt, defocus - correctable by alignment)
|
||||
- **Reference orientation**: 20° zenith angle (Subcase 2)
|
||||
|
||||
### 8.2 Weighted Sum Formula
|
||||
|
||||
The weighted objective combines three metrics:
|
||||
|
||||
$$J = \sum_{i=1}^{3} \frac{w_i \cdot f_i}{t_i}$$
|
||||
|
||||
Where:
|
||||
- $w_i$ = weight (5.0, 5.0, 1.0)
|
||||
- $f_i$ = objective value (nm)
|
||||
- $t_i$ = target value (4, 10, 20 nm)
|
||||
|
||||
### 8.3 Algorithm
|
||||
|
||||
- **Optimizer**: TPE (Tree-structured Parzen Estimator)
|
||||
- **Startup trials**: 15 random
|
||||
- **EI candidates**: 150
|
||||
- **Multivariate modeling**: Enabled
