Abstract
In mining and its similar industries, compact excavators are used commonly in narrow working spaces, of which bucket must be rotated essentially. Considering of those applications, many kinds of the compact excavators have been developed, but any stress evaluation of bucket rotating part had not been attempted. In this study, using of the finite element method and Spare solver, stress analysis has been performed on the bucket rotating parts and its adjacent parts of compact excavator, with using an excavation stress model, in various directions and positions. Resultantly, it has been defined that stress of connector in the rotating part is a little higher, due to its shape, than those remained parts of which stress are shown equally as 1 MPa. Especially in the moving parts, the stress of bucket pin and rotating pinion gear has been calculated as 7.7 MPa and 40 MPa respectively.
