  • Model an Excavator Dipper Arm as a Flexible Body - MATLAB

    This example uses the Partial Differential Equation Toolbox™ to create a reduced-order model for a flexible dipper arm, such as the arm for an excavator or a backhoe. You start with the CAD geometry of the dipper arm, generate a finite-element mesh, apply the Craig-Bampton FEA substructuring method, and generate a reduced-order model.

  • 7 Different Excavator Bucket Types and Their Uses – Also

    Here are seven types of excavator bucket types and their uses: Type #1: Digging Excavator Bucket. When one thinks of an excavator, the large, claw-looking attachment comes to mind. This attachment is colloquially known as the digging bucket. It, as its name suggests, is primarily used for digging through hard, rugged surfaces.

  • Optimal Design of Hydraulic Excavator Shovel Attachment

    Abstract: The optimal design of TriPower shovel attachment remains a challenging task although TriPower face shovel excavators work well in mines all over the world. To address this issue, we establish the multiobjective optimization model of TriPower shovel attachment, which sets three kinematic indicators and two mechanical indicators as the objective functions.
