Dynamic Gear Testing Methods
Linking gear geometry to real-world NVH behaviour through dynamic testing and signal analysis – paving the way for function-driven tolerance definitions.
Project description
This project investigates the link between gear geometry and functional behaviour by combining traditional geometric measurement with dynamic single-flank testing and FFT-based signal analysis. The study maps how individual gear parameters influence NVH under real operating conditions.
Impact
By connecting geometric deviations to measurable functional effects, this project lays the groundwork for function-oriented tolerance definitions, potentially enabling manufacturers to relax certain geometric requirements without compromising performance, reducing both production costs and rejection rates while maintaining or improving powertrain NVH characteristics.
