Static/Dynamic Balance Measurement TRIZ Cases
- Doubly-fed wind turbine blade imbalance detection via stator current
Stator current analysis detects blade imbalance in doubly-fed wind turbines using Hilbert and FFT transforms.
- Balancing Machine Calibration for Rotor Resonance Correction
Calculated rotor natural frequencies correct permanent calibration errors near resonance, enabling higher speed measurements with minimal error.
- Eddy Current Sensors for Aircraft Landing Gear Weight
Eddy current sensors measure magnetic permeability in landing gear structural elements to determine aircraft weight distribution.
- Continuous Wheel Weight Dispensing and Cutting System
A continuous strip of wheel weight material enables precise length-based dispensing for arbitrary balancing weights.
- Machining Axis Determination Using Reference Workpiece Comparison
Comparing surface points against a reference workpiece determines the machining axis, reducing device complexity while maintaining high precision.
- Golf Ball Center of Gravity Marking via Rotational Positioning
Rotating mechanism aligns golf ball center of gravity for precise surface marking, eliminating immersion steps and preserving visual aesthetics.
- Polar Plot Imbalance Analysis for Rotating Components
Two-dimensional polar plot assesses measurement error and identifies unknown imbalance sources through correlation analysis across processing operations.
- Center-of-mass height estimation using suspension bearing capacity
A center-of-mass height estimation device calculates sprung mass height via roll moment and lateral acceleration data.
