Numerical simulation analyzes digging resistance in excavators, suggesting strategies to enhance efficiency.

The research aims to optimize excavator performance by analyzing digging resistance characteristics during soil excavation.
Established a numerical simulation model using the arbitrary Lagrangian–Eulerian method.
Conducted orthogonal experiments to study the influence of excavation parameters.
Determined optimal digging trajectories and resistance characteristics under various conditions.
Increasing the excavation angle from 36° to 48° reduces X-direction resistance and moment significantly by approximately 39.48% and 38.85%.
Optimizing arm movement speed further decreases resistance and moment.
Achieving optimal digging resistance and specific energy consumption requires specific parameters for hydraulic cylinder displacement and movement intervals.
