Implication

Experimental study identifies energy inefficiencies in hydraulic excavators linked to operator behavior, highlighting design and training improvements.

Key Points

This study aims to clarify the impact of operator behaviors and driving modes on energy flow loss in hydraulic excavators.
Data-driven framework based on real-time field measurements
Parameterization of operator control behaviors and predefined control strategies
Evaluation of energy flow loss across different swing amplitudes during excavation operations.
For 90° swings, medium-opening style reduces energy consumption by 15.6% compared to large-opening style while maintaining cycle time.
For 180° swings, medium-opening style improves efficiency by 29.3% and reduces energy use by 17.7% relative to small-opening style.
The heavy-load driving mode increases system efficiency by 28.3% but raises total energy consumption by 105.2%.
