Structural Strength Optimization of Excavator Stick

Optimized cross-section geometry and wall thickness improve bending and torsional rigidity while reducing overall weight.

Strategic placement of stiffeners and reinforcement plates distributes stress more evenly and minimizes the risk of cracking.

High-strength, wear-resistant steel is used in key load-bearing areas to extend fatigue life.

Improved design of hinge lugs and bushings reduces localized compression and shear deformation.

Enhanced welding processes and weld layout help minimize residual welding stress and improve structural reliability.

Finite Element Analysis (FEA) is used to accurately identify weak points and apply targeted reinforcement.

Optimized hydraulic cylinder mounting positions improve load angles and overall force distribution.

Smooth radius transitions at the stick base and corner joints prevent stress concentration caused by sharp edges.

Lightweight structural design reduces plate thickness in non-load-bearing areas while maintaining structural strength.

Reinforced impact- and fatigue-resistant structure ensures durability under heavy-duty earthmoving and rock excavation conditions.
