In order to study the static and dynamical characteristics of the crankshaft, ANSYS software was used to carry out the corresponding calculations. The entity model of the crankshaft was established by UG software firstly, and then was imported into ANSYS software for meshing, and then the finite element model of the crankshaft was constructed. The crankshaft satisfied the requirement of stiffness and strength through static analysis. The top six natural frequencies and corresponding shapes were acquired through modal analysis, and the every order critical rotating speed of the crankshaft was calculated. The fatigue life of the crank was calculated by fatigue module of ANSYS software finally. These results offered the theoretical guidance for designing, manufacturing and repairing the crankshaft.

The CAD software was used to establish 3D model of frame of dump truck, and the finite element model was established through Hyper Mesh. The stress distributions of the frame in vertical accelerating, turning, twisting and climbing conditions were computed through finite element software when the dump truck was loaded 80t. The result is consistent with the actual situation of the frame, which proved that the approach of finite element analysis is feasible. And we proposed the improved method of the frame according to finite element results.

In this paper, authors made contrast with the three finite element methods in analysis accuracy and usability .Those are all based on the structural analysis of mining excavator arm. The first fem is using UG solid modeling capabilities to create model .The finite element model is generated by UG_ANSYS, including setting the loads of material properties and boundary conditions ,also loading work. The process is called preprocessing completely .Then export a“. inp” file,after that, imported that file directly into ANSYS software for solving. The second one is to import solid mode created in UG into ANSYS software directly ,then take pretreatment and solution accordingly.The last one is using UG modeling and UG NX NASTRAN (the finite element analysis function) for structure analysis. It is concluded that using UG completely pretreatment of ANSYS analysis method and UG NX NASTRAN method feel more convenient to operate it with the high analyze accuracy,with the two methods , designers can modify mining mechanical arm weak positions more easily.In turns,they can improve the designing level of physical prototyping.
