vamseeachanta Signal Quality (+2)
Signal Quality
- Check sampling rate - Ensure Nyquist criterion for frequencies of interest
- Remove transients - Skip build-up periods in OrcaFlex simulations
- Validate stationarity - Use multiple segments for PSD estimation
- Handle gaps - Interpolate or segment around missing data
Rainflow Analysis
- Hysteresis filtering - Remove small cycles (typically < 1-5% of range)
- Residual handling - Choose appropriate method for incomplete cycles
- Cycle binning - Use consistent bin sizes for histogram comparison
- S-N curve matching - Ensure stress units match S-N curve units
Performance Optimization
- Parallel processing - Use batch extraction for multiple files
- Memory management - Process long signals in chunks
- Downsampling - Reduce sampling rate if high frequencies not needed
- Result caching - Store intermediate results for reprocessing
