In this paper, iron ladle stress and deformation has been accurately calculated using finite element analysis software ANSYS based on 260t iron ladle in standing, lifting, tipping working conditions. Distribution of stress field was obtained. The stiffness and strength of the iron ladle has been evaluated. The results show that the iron ladle in the standing, lifting and tipping working conditions, structural deformation is small, the strength and stiffness meet the requirements. This research extends the working life of 260t iron ladle. It provides theoretical basis for producing and using of the iron ladle and further optimal designing.

The finite element analysis method of falling-object protective structure (FOPS) for the loader is presented in this paper. Taking FOPS for CL958 type loader as an example, this paper builds the analysis model in ANSYS, obtains the displacement of the load center and the maximum deformation of FOPS caused by the impact load and proves the safety by the drop test. It provides the theoretical basis and design principle for the optimization design and reliability design of FOPS for the loader.

Distribution Of Stress

The objective of the present study is to evaluate how the elastic properties of the fabrication material of dental implants influence peri-implant bone load transfer in terms of the magnitude and distribution of stress and deformation. A three-dimensional (3D) finite element analysis was performed; the model used was a section of mandibular bone with a single implant containing a cemented ceramic-metal crown on a titanium abutment. The following three alloys were compared: rigid (Y-TZP), conventional (Ti-6Al-4V), and hyperelastic (Ti-Nb-Zr). A 150-N static load was tested on the central fossa at 6° relative to the axial axis of the implant. The results showed no differences in the distribution of stress and deformation of the bone for any of the three types of alloys studied, mainly being concentrated at the peri-implant cortical layer. However, there were differences found in the magnitude of the stress transferred to the supporting bone, with the most rigid alloy (Y-TZP) transferring the least stress and deformation to cortical bone. We conclude that there is an effect of the fabrication material of dental implants on the magnitude of the stress and deformation transferred to peri-implant bone.

Modes Of Vibration

In this paper, the finite element analysis for stress/deformation/modes of vibration for the centrifugal fan impeller with constant thickness backward-curved blades using CATIA software will be presented. The principal steps of the finite element analysis procedure using CATIA/Generative Structural Analysis environment will be presented: creating the 3D model; configuring the mesh; applying the restraints; applying the loads; running the numerical static analysis and the numerical frequency analysis; interpreting the results and observing the modes of vibration correlating with the impeller mode shape. This procedure will be used for 4 different centrifugal fan impellers according with the 4 blade design methods and the results will be comparatively analyzed. For each design method, two materials will be used: steel with density of 7860 kg/m3 and aluminium with density of 2710 kg/m3. Two important results have been obtained after the structural analysis: under the working conditions considered for the analysis, all 4 blade design methods leads to impellers with very good mechanical behaviour; any frequency of the main modes of vibrations for all blade design methods and for both materials is not in phase with the impeller speed, thus the possibility of resonance being eliminated.
