Fatigue Analysis and Design Optimization of Excavator Bucket

Abstract

Construction activity is continually rising, and the strong performance of construction equipment ensures rapid expansion in the earth moving machine sectors. This study focuses on the method for calculating the digging forces needed to dig the terrene for minor building work. This approach calculates the force and is also used to perform a fatigue analysis to determine the bucket's fatigue life and failure rate. Because the current excavator arm mechanism is subjected to deformation and bending forces during lifting and digging operations, failure at the bucket end of the arm happens frequently. The excavator arm is analysed using ANSYS workbench software at current digging force and lifting capacity. An analytical approach has also been provided for static force analysis of excavator bucket.
