Abstract
Excavators are earth moving equipment used in excavating hard rocks and soil underneath the natural surface of the ground. Due to unpredictable conditions the excavator parts like boom, arm, bucket, and bucket teeth are subjected to high loads. During the excavation operation, there is an obscure resistance forces offered by the terrain to bucket teeth, which in turn are passed on to arm of the excavator. These forces have an adverse effect on the excavator. Thus, the excavator parts are made with high strength, which makes the parts heavy. This in turn increases the initial fabrication cost and operating cost due to heavier operating parts. Therefore, this work deals with optimizing the design and conducting FEA to existing excavator arm. In this work, finite element analysis (FEA) of existing excavator arm is compared with optimized arm for stresses and deflection. This chapter discusses finite element-based optimization of excavator arm, and the most appropriate design is identified. Further model analysis is performed to check stability in the model and compared with the existing model.
