Abstract
In this paper, the actual working conditions in the excavator bucket load in the mining process and foreign load has random features of Pro/E and finite element analysis software ANSYS to establish the bucket entity model, based on rock mechanics, material nonlinear analysis theoretical Construction of the soil constitutive model simulation, and the bucket of the different movement of the force, respectively bucket two main conditions the stress and displacement contours and analysis of the ultimate stress values and bucket stress characteristics is to improve the bucket force and work performance, improve safety and efficiency of the bucket work to provide a basis.
