Optimization of bucket tooth excavator design using topology optimization and finite element method

Purpose: This research discusses the optimization design of bucket tooth on the market to produce a lighter design but still maintains its strength, the type of bucket tooth is Verona PC200. Methodology: The optimization process in a bucket tooth applies the concept of topology optimization. A static linear analysis is performed using the finite element method to see the maximum stress that occurs in the bucket tooth. Then the method is determining the design variable of bucket tooth with applied a manufacturing constraint. Optimization gives the new design. Result: The maximum VonMises value is 403.81 MPa. After that topology optimization is done by selecting several variations of the design area which results in a reduction in mass in first variation of 0.72 kg and the second variation 1.49 kg. The mass reduction causes a change in stress that occurs in the bucket tooth to 451.8 MPa in first variation and 458.6 MPa in variation 2, but the stress is still in a safe condition. Value: Optimization of bucket tooth design in this paper can reduce the cost of production for bucket tooth with considering to keep the strength of bucket tooth.
